A New Window on the Hα Luminosity Function and Star Formation Rate Density from 1.2 < z < 6.6 from JWST Medium-Band Photometry
Nicholas S. Martis, Chris Willott, Gregor Rihtaršič +23
We present the first self-consistent measurement of the Hα luminosity function over a wide redshift range, covering cosmic noon into the epoch of reionization. Our analysis utilize…
Interaction-induced star formation boosts stellar mass assembly in galaxies
Kiyoaki C. Omori, Marcin Sawicki, Rosa M. Mérida +10
Galaxy interactions are a key ingredient in galaxy evolution; not only are they a primary pathway of galaxy growth and mass assembly, but also a key driver of processes such as sta…
JWST Reveals Two Overmassive Black Hole Candidates in Dwarf Galaxies at z 0.7: Pushing Black Hole Searches into the Dwarf-Galaxy Regime
E. Iani, P. Rinaldi, A. Torralba +35
We report the discovery and characterization of two compact galaxies, Pelias and Neleus, at z ~ 0.71 and z ~ 0.75, identified in MACS J0416.1-2403 and GOODS-North. Both exhibit unu…
Effects of Environment on the Size Evolution of Quiescent Galaxies: Comparing Galaxies in Clusters and in the Field at Two Rest-frame Wavelengths
Angelo George, Ivana Damjanov, Marcin Sawicki +9
We investigate the impact of environment on quiescent galaxy (QG) size evolution using the CLAUDS+HSC imaging covering 18.6~deg in five broad filters () and the effectiv…
RIDEN pilot survey: broad-band selection of candidate quasars with extended Lyman- nebulae using CLAUDS-HSC-SSP-DUNES joint data
Rhythm Shimakawa, Satoshi Kikuta, Haruka Kusakabe +5
The Vera C. Rubin Observatory will conduct the Legacy Survey of Space and Time (LSST), delivering deep, multi-band () imaging data across 18,000 square degrees over the nex…
The Growth of Galaxy Stellar Haloes Over
Devin J. Williams, Ivana Damjanov, Marcin Sawicki +9
Galaxies are predicted to assemble their stellar haloes through the accretion of stellar material from interactions with their cosmic environment. Observations that trace stellar h…
