The LEGA-C of nature and nurture in stellar populations of galaxies at z~0.6-1.0: D4000 and H-delta reveal different assembly histories for quiescent galaxies in different environments
David Sobral, Arjen van der Wel, Rachel Bezanson +11
Galaxy evolution is driven by a variety of physical processes which are predicted to proceed at different rates for different dark matter haloes and environments across cosmic time…
J-PLUS: Uncovering a large population of extreme [OIII] emitters in the local Universe
A. Lumbreras-Calle, C. López-Sanjuan, D. Sobral +17
Over the past decades, several studies have discovered a population of galaxies undergoing very strong star formation events, called extreme emission line galaxies (EELGs). In this…
Quantifying the Poor Purity and Completeness of Morphological Samples Selected by Galaxy Colour
Rebecca J. Smethurst, Karen L. Masters, Brooke D. Simmons +7
The galaxy population is strongly bimodal in both colour and morphology, and the two measures correlate strongly, with most blue galaxies being late-types (spirals) and most early-…
Evidence for anisotropic quenching in massive galaxy clusters at
John P. Stott
A recent observational result finds that the quenching of satellites in groups at has an angular dependence relative to the semi-major axis of the central galaxy. This obs…
Modelling high-resolution ALMA observations of strongly lensed dustystar forming galaxies detected by Herschel
Jacob Maresca, Simon Dye, Aristeidis Amvrosiadis +15
We present modelling of ~0.1arcsec resolution Atacama Large Millimetre/sub-millimeter Array imaging of seven strong gravitationally lensed galaxies detected by the Herschel Space O…
Black hole virial masses from single-epoch photometry: the miniJPAS test case
Jonás Chaves-Montero, Silvia Bonoli, Benny Trakhtenbrot +25
Precise measurements of black hole masses are essential to understanding the coevolution of these sources and their host galaxies. We develop a novel approach for computing black h…
Euclid preparation: XVIII. Cosmic Dawn Survey. Spitzer observations of the Euclid deep fields and calibration fields
Andrea Moneti, H. J. McCracken, M. Shuntov +194
We present a new infrared survey covering the three Euclid deep fields and four other Euclid calibration fields using Spitzer's Infrared Array Camera (IRAC). We have combined these…
Practical Galaxy Morphology Tools from Deep Supervised Representation Learning
Mike Walmsley, Anna M. M. Scaife, Chris Lintott +9
Astronomers have typically set out to solve supervised machine learning problems by creating their own representations from scratch. We show that deep learning models trained to an…
(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…
Ubiquitous [OII] Emission in Quiescent Galaxies at z ~ 0.85
Michael V. Maseda, Arjen van der Wel, Marijn Franx +12
Using deep rest-frame optical spectroscopy from the Large Early Galaxy Astrophysical Census (LEGA-C) survey, conducted using VIMOS on the ESO Very Large Telescope, we systematicall…
Towards precise galaxy evolution: a comparison between spectral indices of galaxies in the IllustrisTNG simulation and the LEGA-C survey
Po-Feng Wu, Dylan Nelson, Arjen van der Wel +13
We present the first comparison of observed stellar continuum spectra of high-redshift galaxies and mock galaxy spectra generated from hydrodynamical simulations. The mock spectra…
Metal-enriched halo gas across galaxy overdensities over the last 10 billion years
Rajeshwari Dutta, Michele Fumagalli, Matteo Fossati +15
We present a study of metal-enriched halo gas traced by MgII and CIV absorption at z<2 in the MUSE Analysis of Gas around Galaxies survey and the Quasar Sightline and Galaxy Evolut…
Stellar Dynamical Models for 797 Galaxies from LEGA-C
Josha van Houdt, Arjen van der Wel, Rachel Bezanson +12
We present spatially resolved stellar kinematics for 797 galaxies selected from the LEGA-C survey and construct axisymmetric Jeans models to quantify their dynamical mass…
Kiloparsec-scale AGN Outflows and Feedback in Merger-Free Galaxies
Rebecca J. Smethurst, Brooke D. Simmons, Alison Coil +7
Recent observations and simulations have challenged the long-held paradigm that mergers are the dominant mechanism driving the growth of both galaxies and supermassive black holes…
The miniJPAS survey: the photometric redshift catalogue
A. Hernán-Caballero, J. Varela, C. López-Sanjuan +30
MiniJPAS is a ~1 deg^2 imaging survey of the AEGIS field in 60 bands, performed to demonstrate the scientific potential of the upcoming JPAS survey. Full coverage of the 3800-9100…
Galaxy Zoo: 3D -- Crowd-sourced Bar, Spiral and Foreground Star Masks for MaNGA Target Galaxies
Karen L. Masters, Coleman Krawczyk, Shoaib Shamsi +15
The challenge of consistent identification of internal structure in galaxies - in particular disc galaxy components like spiral arms, bars, and bulges - has hindered our ability to…
Galaxy Zoo: Stronger bars facilitate quenching in star forming galaxies
Tobias Géron, R. J. Smethurst, Chris Lintott +4
We have used Galaxy Zoo DECaLS (GZD) to study strong and weak bars in disk galaxies. Out of the 314,000 galaxies in GZD, we created a volume-limited sample (0.01 < z < 0.05, Mr < -…
