How to Craft the Right Language AI Policy For Your Research Group (Some Assembly Required)
Michelle Ntampaka, S. Burke-Spolaor, Ioana CiucÄ +14
Language AI is rapidly becoming part of the astronomy research ecosystem, prompting research teams to develop policies governing its use. But resources and advice for AI adoption a…
On the correlation between globular clusters and the distribution of dark matter in galaxy clusters: the case of Abell 2744
Marta Reina-Campos, Joshua S. Speagle, William E. Harris
Globular clusters (GCs) lie scattered around the inner of the virial radius of galaxy clusters, potentially being excellent tracers of the underlying mass distribution. In t…
Finding the boundary: Using galaxy membership to inform galaxy cluster extent through machine learning
Christine Hao, Stephanie O'Neil, Mark Vogelsberger +3
The spatial extent of the environment's impact on galaxies marks a transitional region between cluster and field galaxies. We present a data-driven method to identify this region i…
It's More Complicated Than You Think: A Forward Model to Infer the Recent Star Formation History, Bursty or Not, of Galaxy Populations
Emilie Burnham, Bingjie Wang, Joel Leja +14
Observations of the early Universe (z > 4) with the James Webb Space Telescope reveal galaxy populations with a wide range of intrinsic luminosities and colors. Bursty star formati…
An Ancient Descendant of the First Galaxies
Jacqueline Antwi-Danso, Adam Muzzin, Luke Robbins +18
JWST has revealed unexpectedly bright galaxies in the first 500 Myr after the Big Bang. Their overabundance suggests that they are preferentially observed during burst phases, wher…
Data-Driven Stellar Spectral Modelling with GSPICE
Douglas P. Finkbeiner, Joshua S. Speagle, Tanveer Karim
Spectral data reduction pipelines deal with a wide variety of challenges including masking cosmic rays, calibrating wavelength solutions, and estimating background noise while tryi…
