Episode 12 – Signs of life, little red dots and the links between star clusters and high redshift galaxies
This episode, Michelle and Payel are very on-theme as they discuss whether Little Red Dots can be explained by super Eddington accretion; the high abundances of nitrogen to oxygen in the most distant galaxies and whether this is tied to globular cluster formation; the stellar graveyard in galaxies, and claims of signs of life in…

Episode 11: Whirling planes, wandering black holes and alien supernovae
In this episode, Michelle and Payel discuss whether wandering intermediate black holes are mythical or not, how planes of satellites may form from cosmic accretion, how to form double hot Jupiters, whether Kelper’s supernova remnant is an ‘alien’, whether Unions I is the faintest star cluster or the faintest galaxy, and just how old our…

Episode 10 – Mixing dark matter, surviving black holes and hunting for planets
This episode, Michelle and Payel delve into the latest constraints on mixed dark matter from the Lyman alpha forest, what happens to stars that get a little too close to a black hole, how machine learning can help identify stars likely to host an Earth-like planet, studying the dark ages from the Moon and witnessing…

Episode 9 – slowing bars, growing black holes, pasta sauces and AI
In this episode, Payel and Michelle discuss how you can slow down a galaxy’s bar, scaling relations for black holes, whether we can use intracluster light to learn about dark matter, little red dots, AI cosmologists and pasta sauce for all your plotting needs! Check out our episode – and the papers that inspired it…

Episode 8 – Cosmology, pulsars and dark matter in disk galaxies
In this episode, Payel and Michelle discuss the longest period pulsar, the formation of nuclear star clusters, the recent data releases from ACT and DESI, dark spiral arms and the problem with rotation curves. Papers in this episode: The discovery of a 41-second radio pulsar PSR J0311+1402 with ASKAP – Yuanming Wang et al. Seeding…

Episode 7: black holes, stealthy satellites and the distance to DF2
In this episode of The Starxiv, Michelle and Payel discuss a revised distance for the controversial ultra-diffuse galaxy, DF2; a discovery of a supermassive black hole in an ultra compact dwarf; 2 galaxies hiding in plain sight; and how statistical mechanics may help with dark matters cusp-core problem. Michelle and Payel also have to put…

Episode 6: Einstein rings, black holes and ringed galaxies
In this episode, Payel and Michelle delve into the arXiv and discuss standard sirens, gravitational lenses, a very metal poor stellar stream and a cosmic bullseye! Candidate intermediate-mass black hole discovered in an extremely young low-metallicity cluster in the tadpole galaxy KUG 1138+327 – Wang & Ott Spinning spectral sirens: Robust cosmological measurement using mass-spin…

Episode 5: Galaxies, gas accretion & Aliens
Arriving in your ears on February 10th, our latest installment includes transfer learning to detect low surface brightness galaxies, hot and cold gas accretion, an unusual finding in a filament, details of our proto-Galaxy, and the search for intelligent life! DES to HSC: Detecting low surface brightness galaxies in the Abell 194 cluster using transfer…

Episode 4: January 2025
In this month’s edition, Michelle and Payel dive into the New Year with papers on machine learning, star formation in low mass galaxies and working out just how early in the Universe planets can form. Papers discussed this month: Habitable Worlds Formed at Cosmic Dawn Whalen et al. The puzzle of isolated and quenched dwarf…

Episode 3: December
In this episode, Payel and Michelle discuss six papers covering topics like ultra-diffuse galaxies, the Omega Centauri cluster, and insights from JWST. The extended podcast aims to explore diverse research while transitioning to biweekly episodes in the New Year, maintaining a 30-minute format. They’ll return in 2025.
