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…

UNCOVER/MegaScience Finds Uniform and Highly Bursty Star Formation at 3 < z < 9, consistent with the High-Redshift UV Luminosity Function

Ikki Mitsuhashi, Katherine A. Suess, Joel Leja +24

Star formation timescales are key to understanding fundamental physics like feedback mechanisms, as well as the abundance of bright galaxies at . We investigate galaxy star f…

The Merian Survey: A Statistical Census of Bright Satellites of Milky Way Analogs

Yue Pan, Shany Danieli, Jenny E. Greene +10

We present a statistical census of bright, star-forming satellite galaxies around Milky Way (MW) analogs using the first data release of the Merian Survey. Our sample consists of 3…

Measuring Emission Lines with JWST-MegaScience Medium-Bands: A New Window into Dust and Star Formation at Cosmic Noon

Brian Lorenz, Katherine A. Suess, Mariska Kriek +23

We demonstrate the power of JWST-NIRCam medium-band photometry to measure emission line fluxes and study dust and star formation properties of galaxies at cosmic noon. In this work…

A Spectroscopic Survey of Metal-Poor OB Stars in Local Dwarf Galaxy NGC 3109

Abby Mintz, O. Grace Telford, Evan N. Kirby +3

As JWST uncovers increasingly strong evidence that metal-poor, massive stars in early galaxies dominated reionization, observational constraints on the properties of such stars are…

A Nonparametric Morphological Analysis of H Emission in Bright Dwarfs Using the Merian Survey

Abby Mintz, Jenny E. Greene, Erin Kado-Fong +10

Using medium-band imaging from the newly released Merian Survey, we conduct a nonparametric morphological analysis of H emission maps and stellar continua for a sample of galaxi…
