Abstract: Most things in the universe happen over millions or even billions of years but some things change on the timescales of human life and can be seen to change in a matter of months, days, or even seconds. These are some of the most extreme events in the universe, things like the collapse of a dying star, or a collision of two massive objects. Humans have been observing astronomical transients for centuries, from supernovae to gamma ray bursts and, most recently, gravitational waves. In 2007, we discovered a brand-new type of transient called fast radio bursts, bright radio pulses that last only a few milliseconds. Their origin is one of the newest unsolved mysteries of astronomy. I will tell the story of their discovery and some of the most exciting new breakthroughs.
Bio: Dr Emily Petroff is an astrophysicist jointly appointed as a Veni Fellow at the University of Amsterdam Anton Pannekoek Institute in the Netherlands and as a manager of the CHIME/FRB Collaboration based at McGill University in Canada. She obtained her bachelor’s degree from Carleton College in Northfield, Minnesota and obtained her PhD from Swinburne University of Technology in Melbourne, Australia in 2016. Previously she has worked in the Netherlands as a postdoctoral researcher first at ASTRON, the Netherlands Institute for Radio Astronomy. Her research has made her a leader in the study of fast radio bursts, mysterious distant radio sources that we are just beginning to understand.

As astronomy became increasingly data driven over the twentieth century and we are entering theera of ‘big’ observational astronomy, automated morphological classifications using machinelearning were introduced. In these large surveys, simply curating the data volume becomes asignificant challenge and interesting scientific question in its own right. Machine learning isbecoming an important statistical tool for astronomers seeking to efficiently analyse and derivemeaning from massive data sets, with ‘unsupervised’ methods in particular showing promise invarious applications, particularly in automatic classification.In this work we contribute to the effort of seeking more efficient means of automatically classifying and mining large imaging data sets in the radio using ‘Haralick’ features, which provide a compact representation of image texture.

Title: “Astro-Ecology”: using Astrophysics research techniques to help tackle challenges facing the planet
By: Professor Steve Longmore, Astrophysics Research Institute, Liverpool John Moores University, UK
ABSTRACT & BIO HERE Steve Longmore Talk Sept 23 2021
Abstract:
He will describe how his group are using Astrophysics research techniques to help Ecologists protect the ecosystems, save critically endangered animal species, and stop peat forest fires that are a major contributor to climate change.
Building on technological and software innovations in Astronomy, their “Astro-Ecology” team have developed a drone plus thermal infrared imaging systems and an associated automated detection and identification pipeline that provides a cost-effective and efficient way to automatically detect animals and peat fires. He will describe the current status of the system and their efforts to enable local communities to run routine monitoring and management of animal populations and peat fires over large and inhospitable areas, and thereby tackle global biodiversity loss and climate change.
Astronomy and Astrotourism

ABSTRACT
Astronomy for development is making
great strides in Namibia. Forged by a
collaboration between the Universities of
Oxford and Namibia, together we are using
astronomy as a means for capacitybuilding and to benefit Namibia
socioeconomically. Namibia is already recognised as a world
leader in sustainable tourism; astronomy
offers great potential to expand and
diversify the market with minimal
environmental impact. With access to
some of the darkest and driest skies on the
planet – a completely free resource –
astrotourism is a relatively easy way for
tour guides to complement their earnings.
It also presents an opportunity to preserve
the indigenous stories about the stars,
which are already being lost. With H.E.S.S. already in place and the Africa
Millimetre Telescope on the horizon,
astronomy education provides further
opportunities for sustainable
socioeconomic growth. Led by Radboud
University, we are developing a Social
Impact Plan in the hope to inspire future
generations of Namibian scientists and
engineers.
Bio:
Dr Hannah Dalgleish is a researcher and
communicator, working at the intersection between
astronomy and society. An astrophysicist by training,
she now spends her time focused on capacitybuilding projects, and on furthering our
understanding of how astronomy affects the lives of
people around the world.
Hannah is currently working between the University
of Oxford (UK) and the University of Namibia. She is
a postdoctoral researcher in astronomy for
development, and is involved in numerous projects
related to dark sky tourism and light pollution,
astronomy education, science communication, and
more.

ASB Presentations are held the last Thursday of every month, over Zoom from 6:30 pm until 7:30 pm (unless otherwise stated). These Presentations are open to all society members and their guests and the public at no cost.
Following these Presentations, the ASB committee meets monthly.

MARS- Mokolodi Astronomers Reaching for the Stars – 24 july 2020
On the 24th of July, ASB committee members gathered at Mokolodi Nature Reserve to officially open the new astronomical viewing platform (named MARS – Mokolodi Astronomers Reaching for the Stars), a joint project funded by ASB and Mokolodi, and to unveil a commemorative plaque in honour of the Barrow family of Scotland and the Southport Astronomical Society of the U.K. for their donation of a Celestron 127 SLT Maksutov Cassegrain telescope to the Society. The plaque was donated by Mr. and Mrs. Harold Hester, and Professor Mike Bode, both members of the ASB
Meteorite Landing in Botswana -24 july 2020
On the 24th of July, at 18:30, at the request of the Astronomical Society of Botswana, Dr. Fulvio Franchi from BUIST, gave a presentation via ZOOM about the tracking of a meteorite that landed in Botswana in 2018, and how they eventually recovered several pieces of it in the CKGR after many expeditions looking for it. The fragments are still being tested.
