The MUSE Atlas of Disks (MAD): Ionized gas kinematic maps and an application to Diffuse Ionized Gas
Mark den Brok, C. Marcella Carollo, Santiago Erroz-Ferrer +9
We have obtained data for 41 star forming galaxies in the MUSE Atlas of Disks (MAD) survey with VLT/MUSE. These data allow us, at high resolution of a few 100 pc, to extract ionize…
Photometric properties of reionization-epoch galaxies in the Simba simulations
Xiaohan Wu, Romeel Davé, Sandro Tacchella +1
We study the photometric properties and sizes of the reionization-epoch galaxies in high-resolution Simba cosmological hydrodynamical simulations with box sizes of …
The Recent Burstiness of Star Formation in Galaxies at z~4.5 from H Measurements
Andreas L. Faisst, Peter L. Capak, Najmeh Emami +2
The redshift range z=4-6 marks a transition phase between primordial and mature galaxy formation in which galaxies considerably increase their stellar mass, metallicity, and dust c…
Quenching as a Contest between Galaxy Halos and their Central Black Holes
Zhu Chen, S. M. Faber, David. C. Koo +27
Existing models of galaxy formation have not yet explained striking correlations between structure and star-formation activity in galaxies, notably the sloped and moving boundaries…
Model-independent constraints on the hydrogen-ionizing emissivity at z>6
Charlotte A. Mason, Rohan P. Naidu, Sandro Tacchella +1
Modelling reionization often requires significant assumptions about the properties of ionizing sources. Here, we infer the total output of hydrogen-ionizing photons (the ionizing e…
Beyond UVJ: More Efficient Selection of Quiescent Galaxies With UV / Mid-IR Fluxes
Joel Leja, Sandro Tacchella, Charlie Conroy
The UVJ color-color diagram is a popular and efficient method to distinguish between quiescent and star-forming galaxies through their rest-frame vs. colors. Here we ex…
Rapid Reionization by the Oligarchs: The Case for Massive, UV-Bright, Star-Forming Galaxies with High Escape Fractions
Rohan P. Naidu, Sandro Tacchella, Charlotte A. Mason +3
The protagonists of cosmic reionization remain elusive. Faint star-forming galaxies are leading candidates because they are numerous and may have significant ionizing photon escape…
High redshift JWST predictions from IllustrisTNG: Dust modelling and galaxy luminosity functions
Mark Vogelsberger, Dylan Nelson, Annalisa Pillepich +8
The James Webb Space Telescop (JWST) promises to revolutionise our understanding of the early Universe, and contrasting its upcoming observations with predictions of the CDM mod…
Morphology and star formation in IllustrisTNG: the build-up of spheroids and discs
Sandro Tacchella, Benedikt Diemer, Lars Hernquist +8
Using the IllustrisTNG simulations, we investigate the connection between galaxy morphology and star formation in central galaxies with stellar masses in the range $10^9-10^{11.5}~…
Increasing the Discovery Space in Astrophysics - A Collation of Six Submitted White Papers
G. Fabbiano, M. Elvis, A. Accomazzi +46
We write in response to the call from the 2020 Decadal Survey to submit white papers illustrating the most pressing scientific questions in astrophysics for the coming decade. We p…
Atomic and molecular gas in IllustrisTNG galaxies at low redshift
Benedikt Diemer, Adam R. H. Stevens, Claudia del P. Lagos +9
We have recently developed a post-processing framework to estimate the abundance of atomic and molecular hydrogen (HI and H2, respectively) in galaxies in large-volume cosmological…
Stochastic modeling of star-formation histories I: the scatter of the star-forming main sequence
Neven Caplar, Sandro Tacchella
We present a framework for modelling the star-formation histories of galaxies as a stochastic process. We define this stochastic process through a power spectrum density with a fun…
The MUSE Atlas of Disks (MAD): Resolving Star Formation Rates and Gas Metallicities on < 100pc Scales
Santiago Erroz-Ferrer, C. Marcella Carollo, Mark den Brok +13
We study the physical properties of the ionized gas in local disks using the sample of 38 nearby M Star-Forming Main Sequence (SFMS) galaxies observed so…
A new class of flares from accreting supermassive black holes
Benny Trakhtenbrot, Iair Arcavi, Claudio Ricci +26
Accreting supermassive black holes (SMBHs) can exhibit variable emission across the electromagnetic spectrum and over a broad range of timescales. The variability of active galacti…
