Exploring Astrophysics – Détails, épisodes et analyse

Welcome to episode 30 of exploring astrophysics with me, Vikram Bhamre. Today I am joined by Dr. Kareem El-Badry, a researcher who works mostly in the analysis of binary star systems and has obtained the nickname ‘Black hole destroyer’ for some of his past work. Stay tuned to hear more about that!

Hi everyone, welcome to another episode of exploring astrophysics. Today I am speaking to Dr Lynne Hillenbrand, a professor of Astronomy at Caltech who is an expert in the formation and evolution of young stars and the formation of star clusters. Dr. Hillenbrand spoke to me about trying to learn more about the evolution of these young stars, whose processes are often hidden behind dust and gasses from the Nebula it is in. Her work is partly focus on the properties of the circumstellar disc, a disc of gas and dust that rotates around a young star.

This episode Dr Du spoke about some of her work looking at the physical properties of the interstellar medium in distant galaxies. She also spoke about her interest in asgtronomy outreach and the kind of work she does as outreach manager at the Kavli Institute for Particle Astrophysics and Cosmology. Listen to the end of the podcast to hear her advice on learning more about astronomy at a young age!

Dr Daylan, told me about his work on explanets utilising primarily the TESS mission, and how the transit method is used to discover these planets. Additionally, he also spoke about the charecteristics that can be inferred from a discovered planets, such as the mass, density and orbital radius. 

In this episode Dr Ezzeddine told me about how the chemical and physical compositions of stars can be inferred by the use of spectroscopy. Additionally, she explained what the r-process is, and how by building radiative transfer models we can calculate the abundances of elements in the atmospheres of stars.

Dr Salimpour explained the intersection between art and cosmology, and why he believes those two things are inextricable. He also delved into how the beauty of simplicity underlies all of cosmology.

In this episode, Sven spoke to me about his work in gravitational lensing, and more specifically, a novel statistical analysis method he is developing. He also spoke about how he transitioned to astrophysics from studying math, as well as how his analysis technique could prove incredibly useful in learning more about the matter distribution in our universe.

In this episode, Marcus spoke to me about his current PHD work as well as his interest in cosmology. He explained a little about Astrochemistry and the research he is doing related to it. Lastly, he spoke about the process of getting a PHD and the final outcome required for completion.

Dr Jeffery goes into detail about how dark energy and dark matter, two things he is researching extensively, are elusive and that astrophysicists know very little about it. The Dark Energy Survey is a project which he is part of that tries to map the distribution of dark energy in our universe. Dr Jeffrey also spoke about machine learning in the context of his research and how it is being used extensively throughout the projects he is working in.

This episode I spoke to Dr Doel about some of the projects he has been working on. He told me about the considerations that need to be accounted for when retrofitting telescopes as well as how he entered this field. Dr Doel also described how he thought the field have changed in the past to what it is now.
