UNITSIM-Galaxies: data release and clustering of emission-line galaxies
New surveys such as European Space Agencys (ESA's) Euclid mission are planned to map with unprecedented precision the large-scale structure of the Universe by measuring the 3D positions of tens of millions of galaxies. It is necessary to develop theoretica ...
OXFORD UNIV PRESS2022Origin of stellar prolate rotation in a cosmologically simulated faint dwarf galaxy
Stellar prolate rotation in dwarf galaxies is rather uncommon, with only two known galaxies in the Local Group showing such feature (Phoenix and And II). Cosmological simulations show that in massive early-type galaxies prolate rotation likely arises from ...
OXFORD UNIV PRESS2021The distribution of dark matter and gas spanning 6 Mpc around the post-merger galaxy cluster MS0451-03
Jean-Paul Richard Kneib, David Richard Harvey, Mathilde Jauzac, Baptiste Philippe Klein, Richard Massey
Using the largestmosaic of Hubble Space Telescope images around a galaxy cluster, we map the distribution of darkmatter throughout an similar to 6 x 6 Mpc(2) area centred on the clusterMS 0451-03 (z = 0.54, M-200 = 1.65 x 10(15) M-circle dot). Our joint st ...
OXFORD UNIV PRESS2020Constraining the primordial magnetic field with dwarf galaxy simulations
Pascale Jablonka, Yves Revaz, Mahsa Sanati
Using a set of cosmological hydro-dynamical simulations, we constrained the properties of primordial magnetic fields by studying their impact on the formation and evolution of dwarf galaxies. We performed a large set of simulations (8 dark matter only and ...
EDP SCIENCES S A2020The Pristine Survey - VIII. The metallicity distribution function of the Milky Way halo down to the extremely metal-poor regime
Pascale Jablonka, Carmela Lardo
The Pristine survey uses narrow-band photometry to derive precise metallicities down to the extremely metal-poor regime ([Fe/H]
OXFORD UNIV PRESS2020Analysis of Red Supergiants in VDBH 222
Recent surveys uncovered new young massive clusters (YMCs) that host dozens of red supergiants (RSGs) in the inner Milky Way. These clusters are ideal for studying the most recent and violent star formation events in the inner Galaxy. However, due to the h ...
IOP PUBLISHING LTD2020A survey of the thermal and non-thermal properties of cosmic filaments
In this paper, we exploit a large suite of ENZO cosmological magneto-hydrodynamical simulations adopting uniform mesh resolution, to investigate the properties of cosmic filaments under different baryonic physics and magnetogenesis scenarios. We exploit an ...
OXFORD UNIV PRESS2019Euclid preparation V. Predicted yield of redshift 7 < z < 9 quasars from the wide survey
Georges Meylan, Yi Wang, Richard Massey
We provide predictions of the yield of 7 < z < 9 quasars from the Euclid wide survey, updating the calculation presented in the Euclid Red Book in several ways. We account for revisions to the Euclid near-infrared filter wavelengths; we adopt steeper rates ...
EDP SCIENCES S A2019Preprocessing among the Infalling Galaxy Population of EDisCS Clusters
We present results from a low-resolution spectroscopic survey for 21 galaxy clusters at 0.4 < z < 0.8 selected from the ESO Distant Cluster Survey. We measured spectra using the low-dispersion prism in IMACS on the Magellan Baade telescope and calculate re ...
IOP PUBLISHING LTD2019Evolution of Star-forming Galaxies from z=0.7 to 1.2 with eBOSS Emission-line Galaxies
Jean-Paul Richard Kneib, Zheng Zheng, Johan Comparat, Anand Stéphane Raichoor
We study the evolution of star-forming galaxies with 10(10)M(circle dot) < M-* < 10(11.6)M(circle dot) over the redshift range of 0.7 < z < 1.2 using the emission-line galaxies (ELGs) in the extended Baryon Oscillation Spectroscopic Survey (eBOSS). By appl ...
