The Prevalence of Galaxy Overdensities Around UV-Luminous Lyman Emitters in the Epoch of Reionization

E. Leonova, P. A. Oesch, Y. Qin +19

Before the end of the epoch of reionization, the Hydrogen in the Universe was predominantly neutral. This leads to a strong attenuation of Ly lines of galaxies in th…

Effects of Forcing on Shocks and Energy Dissipation in Interstellar and Intracluster Turbulences

Hyunjin Cho, Dongsu Ryu, Hyesung Kang

Observations indicate that turbulence in the interstellar medium (ISM) is supersonic () and strongly magnetized (), while in the intracluster medium…

H-alpha emission in local galaxies: star formation, time variability and the diffuse ionized gas

Sandro Tacchella, Aaron Smith, Rahul Kannan +6

The nebular recombination line H is widely used as a star-formation rate (SFR) indicator in the local and high-redshift Universe. We present a detailed H radiative transfer s…

VERA astrometry toward the Perseus arm gap

Nobuyuki Sakai, Hiroyuki Nakanishi, Kohei Kurahara +4

The Perseus arm has a gap in Galactic longitudes (l) between 50 and 80 deg (hereafter the Perseus arm gap) where the arm has little star formation activity. To better understand th…

On the Stellar Populations of Galaxies at z=9-11: The Growth of Metals and Stellar Mass at Early Times

Sandro Tacchella, Steven L. Finkelstein, Micaela Bagley +18

We present a detailed stellar population analysis of 11 bright () galaxies at (three spectroscopically confirmed) to constrain the chemical enrichment and growth o…

Evidence from Disrupted Halo Dwarfs that -process Enrichment via Neutron Star Mergers is Delayed by Myrs

Rohan P. Naidu, Alexander P. Ji, Charlie Conroy +10

The astrophysical origins of -process elements remain elusive. Neutron star mergers (NSMs) and special classes of core-collapse supernovae (rCCSNe) are leading candidates. Due t…

(Re)Solving Reionization with Lyα: How Bright Lyα Emitters account for the Cosmic Ionizing Background

Jorryt Matthee, Rohan P. Naidu, Gabriele Pezzulli +12

The cosmic ionizing emissivity from star-forming galaxies has long been anchored to UV luminosity functions. Here we introduce an emissivity framework based on Ly emitters (LAEs…

Dissecting Nearby Galaxies with piXedfit: I. Spatially Resolved Properties of Stars, Dust, and Gas as Revealed by Panchromatic SED Fitting

Abdurro'uf, Yen-Ting Lin, Hiroyuki Hirashita +5

We study spatially resolved properties (on spatial scales of kpc out to at least effective radii) of the stars, dust, and gas in ten nearby spiral galaxies. The prop…

Reproducing the UVJ Color Distribution of Star-forming Galaxies at 0.5 < z < 2.5 with a Geometric Model of Dust Attenuation

Leah Zuckerman, Sirio Belli, Joel Leja +1

We analyze the distribution of rest-frame U-V and V-J colors for star-forming galaxies at 0.5 < z < 2.5. Using stellar population synthesis, stochastic star formation histories, an…

Downstream depolarization in the Sausage relic: a 1-4 GHz Very Large Array study

G. Di Gennaro, R. J. van Weeren, L. Rudnick +10

Radio relics are elongated sources related to shocks driven by galaxy cluster merger events. Although these objects are highly polarized at GHz frequencies (), high-r…

Fast, Slow, Early, Late: Quenching Massive Galaxies at z~0.8

Sandro Tacchella, Charlie Conroy, S. M. Faber +14

We investigate the stellar populations for a sample of 161 massive, mainly quiescent galaxies at with deep Keck/DEIMOS rest-frame optical spectros…
