The LEGA-C galaxy survey: multiple quenching channels for quiescent galaxies at
Angelos Nersesian, Yasha Kaushal, Marco Martorano +9
We analyzed the sizes and star-formation histories (SFHs) of 2908 galaxies with M at , drawn from the LEGA-C survey. The goal is to inves…
LEGA-C stellar populations scaling relations. I: Chemo-archaeological downsizing trends at z~0.7
Anna R. Gallazzi, Stefano Zibetti, Arjen van der Wel +11
We analyze stellar population properties of 552 galaxies at redshift 0.6<z<0.77 from the LEGA-C spectroscopic survey. This first paper in a series presents the catalog of revised a…
Evolution and Mass Dependence of UV-to-near-IR Color Gradients up to z=2.5 from HST+JWST
Marco Martorano, Arjen van der Wel, Andrea Gebek +7
We present the redshift evolution of radial color gradients (in rest-frame and ) for galaxies in the range z $<2.5…
TDCOSMO. XXIII. Measurement of the Hubble constant from the doubly lensed quasar HE1104-1805
Eric Paic, Frédéric Courbin, Christopher D. Fassnacht +18
Time-delay cosmography leverages strongly lensed quasars to measure the Universe's current expansion rate, H_0, independently from other methods. While the latest TDCOSMO results r…
Euclid preparation: LXXXI. The impact of nonparametric star formation histories on spatially resolved galaxy property estimation using synthetic Euclid images
Euclid Collaboration, A. Nersesian, Abdurro'uf +283
We analyzed the spatially resolved and global star formation histories (SFHs) for a sample of 25 TNG50-SKIRT Atlas galaxies to assess the feasibility of reconstructing accurate SFH…
LEGA-C stellar populations scaling relations. II: Dissecting mass-complete archaeological trends and their evolution since z~0.7 with LEGA-C and SDSS
Anna R. Gallazzi, Stefano Zibetti, Arjen van der Wel +11
With a sample of 552 galaxies at z~0.7 from the LEGA-C survey, we investigate how current star formation influences light-weighted mean stellar ages and metallicities, and their me…
