A model for the infrared-radio correlation of main sequence galaxies at gigahertz frequencies and its variation with redshift and stellar mass
Context. The infrared-radio correlation (IRRC) of star-forming galaxies can be used to estimate their star formation rate (SFR) based on the radio continuum luminosity at MHz-GHz frequencies. For its practical application in future deep radio surveys, it i ...
Les Ulis Cedex A2023GOGREEN: A critical assessment of environmental trends in cosmological hydrodynamical simulations at z approximate to 1
Pascale Jablonka, Hung-Hsu Chan
Recent observations have shown that the environmental quenching of galaxies at z & SIM; 1 is qualitatively different to that in the local Universe. However, the physical origin of these differences has not yet been elucidated. In addition, while low-redshi ...
OXFORD UNIV PRESS2023The Local Cluster Survey II: disc-dominated cluster galaxies with suppressed star formation
We investigate the role of dense environments in suppressing star formation by studying log(10)(M- * / M-?) > 9 . 7 star-forming galaxies in nine clusters from the Local Cluster Survey (0.0137 < z < 0.0433) and a large comparison field sample drawn from th ...
OXFORD UNIV PRESS2023A possible dwarf galaxy satellite-of-satellite problem in ?CDM
Dark matter clusters on all scales, and it is therefore expected that even substructure should host its own substructure. Using the Extragalactic Distance Database, we searched for dwarf-galaxy satellites of dwarf galaxies, that is, satellite-of-satellite ...
EDP SCIENCES S A2023The formation of the faintest galaxies in cosmological simulations: from the impact of primordial magnetic fields to the metal enrichment of present day dwarfs by first stars
In the theory of the bottom-up assembly of cosmic structures, one of the main challenges is to connect the smallest, most inconspicuous galaxies we observe today to the building blocks of more massive galaxies such as our own, the Milky Way. Do these so-ca ...
EPFL2023Elastocapillary menisci mediate interaction of neighboring structures at the surface of a compliant solid
Surface stress drives long-range elastocapillary interactions at the surface of compliant solids, where it has been observed to mediate interparticle interactions and to alter the transport of liquid drops. We show that such an elastocapillary interaction ...
2023The GOGREEN Survey: Evidence of an Excess of Quiescent Disks in Clusters at 1.0
Pascale Jablonka, Hung-Hsu Chan
We present the results of the measured shapes of 832 galaxies in 11 galaxy clusters at 1.0 < z < 1.4 from the GOGREEN survey. We measure the axis ratio (q), the ratio of the minor to the major axis, of the cluster galaxies from near-infrared Hubble Space T ...
IOP Publishing Ltd2021Cold gas in the cosmic web around galaxy clusters
Damien Louis Alexandre Spérone-Longin
Galaxies live in very different types of environment. Those different environments are relics from the evolution of the Universe since the Big Bang. This network of structures observed via large scale surveys is called Cosmic Web.
Within this web, galaxies ...
EPFL2021The GOGREEN survey: Internal dynamics of clusters of galaxies at redshift 0.9-1.4
Pascale Jablonka, Hung-Hsu Chan
Context. The study of galaxy cluster mass profiles (M(r)) provides constraints on the nature of dark matter and on physical processes affecting the mass distribution. The study of galaxy cluster velocity anisotropy profiles (beta (r)) informs the orbits of ...
EDP SCIENCES S A2021SEEDisCS: I. Molecular gas in galaxy clusters and their large-scale structure: The case of CL1411.1-1148 at z similar to 0.5
Pascale Jablonka, Gianluca Castignani, Damien Louis Alexandre Spérone-Longin
We investigate how the galaxy reservoirs of molecular gas fuelling star formation are transformed while the host galaxies infall onto galaxy cluster cores. As part of the Spatially Extended ESO Distant Cluster Survey (SEEDisCS), we present CO(3-2) observat ...
