IAA Zoom Lecture 6th Jan 2021 19:30 – Prof Stephen Smartt (QUB)

“Searching for Kilonovae in the nearby Universe” 

The LIGO-Virgo gravitational wave detectors carried out the their third observing run (called O3) during 2019-2020. Many black hole mergers were detected, along with one confident binary neutron star merger and a possible black hole – neutron star system. At the same time, wide-field optical sky surveys are discovering a remarkable diversity in how stars merge, collapse and explode. Only one gravitational wave source has had a discovery of an electromagnetic counterpart.

In 2017 a a pair of merging neutron stars produced what we now call a kilonova (“a thousand novas”!). This was a remarkably fast transient, which decayed in a matter of days.  Many surveys have been searching for these kilonovae without success but given they can be as bright as supernovae they should be detectable irrespective of gravitational wave signals. I will discuss our efforts to uncover this new class of object and reasons why we haven’t found them yet. 

Stephen Smartt is a professor of astrophysics at Queen’s University. He has worked at the Isaac Newton Group of telescopes on La Palma and the University of Cambridge. He leads several international projects, mostly focused on regularly surveying the sky to find anything that changes and his group manage the large scale data processing of two NASA funded surveys. He has discovered supernova progenitors, the faintest supernovae and most luminous explosions as well as mergers of compact stars. In 2018 he was awarded the Royal Irish Academy’s Gold Medal and was elected a Fellow of the Royal Society in 2020.

IAA ZOOM LECTURE – WEDS 16th DEC 19:30 – Dr Gavin Ramsay – “Gravitational Wave Optical Transient Observer”

Abstract:
The direct detection of gravitational waves from merging black holes and neutron stars using the Ligoand Virgo detectors is one of humankind’s greatest triumphs. However, the exact position in the skyof these bursts is not well constrained, often to within hundreds or more square degrees.

For merging neutrons stars, it was predicted that an electromagnetic counterpart would be visible. If this could be identified then so would the location of the merging event. The Gravitational-wave Optical Transient Observer (GOTO) is a project whose goal is to detect these optical counterparts of gravitational wave events. One prototype has been running on the island of La Palma for more than 2 years, but next year will see a second array on La Palma, with two more nodes in Siding Spring being planned. 


Bio:
Gavin did his PhD at UCL’s Mullard Space Science Laboratory using data from the Rosat X-ray satellite to study magnetic accreting binaries. After several years at the University of Utrecht, he returned to MSSL, and came to Armagh in 2007.

He still studies accreting binaries, but has led several wide field photometric surveys and also uses Kepler and TESS data to study the activity levels of Solar type and low mass stars. He leads Armaghs contribution to the GOTO project.

IAA Zoom Lecture – Weds 18th Nov 19:30 – Dr Jorick Vink

“Thirty Years of Hubble: opening the Treasure Chest”

Synopsis:

Over the last 30 years the Hubble Space Telescope (HST) has spoilt us with the most beautiful, colourful images one can image. In addition to this inspirational role these observations have provided key insights into a vast number of astronomical research fields varying from the formation of planetary systems to Cosmology.

In this talk I attempt to give an overview of some of the most ground-breaking Astrophysical insights that HST has given the world of Astrophysics, revealing the stories behind those pretty pictures. 

Bio:

Jorick Vink started his career at Utrecht University in the Netherlands while also spending an 8 month period at NASA’s Goddard Space Flight Centre.After his PhD, he moved to Imperial College London, before eventually settling at Armagh Observatory in 2007, where he was also Acting Director at the Planetarium during the merger of the two organisations in 2015/16.

He obtained a Visiting Professorship from the University of Leeds in 2017, and is currently President of the IAU Commission of massive stars, and Principle Investigator (PI) of a Large Programme with ESO-VLT complementing the Hubble Space Telescope (HST) ULLYSES Project of massive stars.

IAA Zoom Lecture – Weds 4th November 19:30 – Prof Alan Fitzsimmons

“What makes a comet great?”

Synopsis:

Hopefully, many members of the IAA saw comet NEOWISE this summer. Although it was a great comet to see, it wasn’t a “Great Comet”. That title is reserved to the best and brightest of the comets. But what is it about a comet that can make it a “Great Comet”? This talk will look at the physical and dynamical reasons that make comets “Great”, illustrated by previous apparitions of these magnificent objects.

IAA Zoom Lecture – Weds 21st October – Dr Marc Sarzi, AOP

“The Hunt for Supermassive Black Holes: a Short History”

This highly topical talk by Dr Marc Sarzi, head of research at Armagh Observatory and Planetarium, is highly topical, not only because of the increasing number and variety of Black Holes being discovered, but because of the recent award of the Nobel Prize for physics to three astronomers working on the subject’

SYNOPSIS:

In this talk Dr Sarzi will describe the theoretical and observational milestones that lead to establishing the existence of supermassive black holes, and the award of the 2020 Nobel Prize in physics.

Marc Sarzi graduated in Padua and did his PhD spending time both at the Asiago Observatory in Italy and the Max Plank Institute fur Astronomie in Heidelberg, working at the detection of supermassive black holes using Hubble Space Telescope observations. After his PhD he moved on to post-doctoral research assistant positions in Durham and Oxford, after which he moved to the University of Hertfordshire where he held both a STFC Rutherford research fellowship and a Public Engagement fellowship before finally moving two years ago at the Armagh Observatory & Planetarium as Head of Research.

IAA Zoom Lecture – 7th October 19:30 BST – Nick Howes

“How do you solve a problem like Debris…ahh?”  

Public awareness of the clutter and rubbish humankind is littering our planet and oceans with has never been higher. David Attenborough and Greta Thunberg have firmly established the need to change our behaviour to avoid a catastrophe. But, whilst many companies and consumers are changing their behaviour to avoid plastic waste, a far bigger threat is looming, and one that will be much harder to solve. Currently over 130 million pieces of debris orbit our planet, ranging from microscopic to the size of a bus. 


These are all in an uncontrollable set of orbits, many of the debris objects are smaller than a few cm, and as such, cannot be tracked. Yet, travelling at around 17,000 mph, pieces the size of a pea, could devastate a spacecraft, kill an astronaut, or astro-tourist  and create a knock on effect, creating more and more debris, known as the Kessler Syndrome, famously seen in the Hollywood Movie “Gravity”. 


The impact of this would be devastating to global climate monitoring, defence, navigation, shipping and pretty much every part of our lives. With the launch of the so called “mega” constellations, adding tens of thousands of new satellites, we are at a crisis tipping point. 

Nick Howes, a Fellow of the British Interplanetary Society, Fellow of the Royal Astronomical Society, and Lead Research and Development scientist for a multinational research and engineering company, explains the issues, and possible ways to stop this from happening.

The meeting will be hosted on Zoom.us and where possible will be simulcast on YouTube.

 “Observing the Radio Universe from Birr, Co. Offaly” by Prof Peter Gallagher, Head of Astronomy and Astrophysics at the Dublin Institute for Advanced Studies.

Synopsis  The Irish Low Frequency Array (I-LOFAR; www.lofar.ie) was installed at Birr Castle, Co. Offaly in 2017 and now links Ireland into the largest low frequency radio telescope in the world, stretching nearly 2,000 km from the Irish Midlands to eastern Poland .

LOFAR is already giving us new views of astronomical phenomena such as solar flares, exoplanets, star-forming regions and rapidly rotating stars called pulsars. In this talk, I will given an overview of the building of I-LOFAR and the recent scientific insights that this unique telescope is providing.”   

Prof Gallagher is now effectively at the top of the tree in astronomy in Ireland . Formerly professor in TCD specialising in solar physics, he was appointed head of the astrophysics section of DIAS last year. He was almost single-handedly responsible for getting I-LOFAR approved, funded, designed, installed and operational. It’s now the only astronomical facility producing top-end astronomical research results from the island of Ireland .

A SKY FULL OF SHOOTING STARS

IAA MEDIA RELEASE:Irish Astronomical Association

The annual Perseid Meteor Shower peaks on Tuesday and Wednesday, and with not too much interference from Moonlight, the conditions are good this year. All we need is a clear sky! Meteors, commonly called ‘shooting stars’, or ‘falling stars’, are not stars at all, but tiny bits of debris released from the surface of comets as they orbit the Sun. When the Earth happens to pass through one of these streams of debris as we orbit the Sun, we collide with those little particles at very high speed – about 60 miles per second – and they get burned away in our upper, giving the flash of light we see as a meteor. 

You may also see some starlike objects moving across the sky much more slowly: they are artificial satellites. But meteors move much more swiftly – usually lasting for no more than a second or so. Most are about as bright as the average stars, but if you observe for long enough you will probably see a really bright one, much brighter than any of the stars: these ones are called ‘fireballs’.  

The Perseids are so called because they all appear to come from the direction of the constellation Perseus, but they can actually appear anywhere in the sky. The Third Quarter moon will rise just after midnight on Tuesday night, and that will spoil the view a bit, so try to observe from a spot where the Moon is hidden by a tree or building, or at least look in the opposite direction. The best part of the sky to look at is either North or South to avoid the Moon once it rises, or almost directly overhead if that’s comfortable; choose the area that is darkest and clearest from wherever you are observing. Next night it will rise later, and won’t be so bright.   You should also choose a location as far away from artificial lights, particularly big town and city lights, and allow time for your eyes to adapt to the dark – at least 15 minutes if going out from a bright room. The shower is active through the first half of August, but maximum activity will occur on Tuesday and Wednesday, nights. 

The activity then dies away gradually over the following few days. The number of meteors seen will increase during each night as the constellation Perseus rises higher in the sky in the North East, and if you are keen enough to keep going into the early hours of the morning you could see a meteor about every minute or so on Wednesday night, from a dark location. While you are out, look for brilliant Jupiter low down in the southern sky, and close to the left, Saturn. It’s not as bright as Jupiter, but it’s brighter than most of the stars. And later in the night, around midnight, look to see brilliant ruddy Mars rising in the East – it’s about midway in between Jupiter and Saturn. 

IMAGING: You can try photographing the Perseids with any modern digital camera which can give long timed exposures: set to the widest angle if it’s a zoom lens, set the focus to infinity, set the ISO to a high value, and give exposures of a few minutes or so, until the sky brightness starts to fog over the whole image – you’ll just have to experiment with that. If you have a wide-angle lens, use that. Point the camera about 50 degrees above the horizon, and watch to make sure the lens does not get covered with dew!You will then have to check your images on a computer screen afterwards to see if you have caught any – it’s not as easy as visual observing, as your eyes can cover a much wider area of the sky. 

THE GOOD NEWS!Firstly, you don’t need any special equipment – just your own eyes. For comfort, it’s best to use a recliner or garden lounger so you can look up at the sky for a long time without getting a sore neck, and wrap up warm.   Secondly, you can observe from anywhere in the country, but do try to get to a spot where the sky is fairly dark, and where you won’t be bothered by vehicle lights either. For more information see: www.irishastro.org
