Subhalo abundance matching through the lens of a hydrodynamical simulation
We use the IllustrisTNG100 hydrodynamical simulation to study the dependence of the galaxy two-point correlation function on a broad range of secondary subhalo and galactic properties. We construct galaxy mock catalogues adopting a standard subhalo abundan ...
OXFORD UNIV PRESS2022The Pristine survey - XV. A CHIT ESPaDOnS view on the Milky Way halo and disc populations
Pascale Jablonka, Willem Suter, Carmela Lardo, Romain Ely Roland Lucchesi
We present a one-dimensional, local thermodynamic equilibrium homogeneous analysis of 132 stars observed at high resolution with ESPaDOnS. This represents the largest sample observed at high resolution (R similar to 40 000) from the Pristine survey. This s ...
OXFORD UNIV PRESS2022The infrared-radio correlation of star-forming galaxies is strongly M-star-dependent but nearly redshift-invariant since z similar to 4
Over the past decade, several works have used the ratio between total (rest 8-1000 mu m) infrared and radio (rest 1.4 GHz) luminosity in star-forming galaxies (q(IR)), often referred to as the infrared-radio correlation (IRRC), to calibrate the radio emiss ...
2021Doppler-based positioning using LEO augmented satellite constellation - Simulations of perspectives
The Global Navigation Satellite System (GNSS) refers to a constellation of satellites emitting signals from space, used to provide Position, Navigation and Timing (PNT) services to the receivers on Earth. Nowadays, the GNSS is exploited in a wide range of ...
2020The Pristine survey IV: approaching the Galactic metallicity floor with the discovery of an ultra-metal-poor star
Pascale Jablonka, Nicolas Lawrence Etienne Longeard, Carmela Lardo, Marc Gentile
The early Universe presented a star formation environment that was almost devoid of heavy elements. The lowest metallicity stars thus provide a unique window into the earliest Galactic stages, but are exceedingly rare and difficult to find. Here, we presen ...
OXFORD UNIV PRESS2018The last stages of star formation in the dwarf spheroidal galaxy Sextans
This thesis is anchored in the research of better understanding of the chemical evolution of galaxies. Many dwarf spheroidal galaxies (dSph) are orbiting the Milky Way displaying various star formation histories. The formation of these dwarf galaxies and t ...
EPFL2015An extended Herschel drop-out source in the center of AS1063: a normal dusty galaxy at z=6.1 or SZ substructures?
Jean-Paul Richard Kneib, Benjamin Yvan Alexandre Clement, Johan Richard
In the course of our 870 mu m APEX/LABOCA follow-up of the Herschel Lensing Survey we have detected a source in AS1063 (RXC J2248.7-4431) that has no counterparts in any of the Herschel PACS/SPIRE bands, it is a Herschel "drop-out" with S-870/S-500 >= 0.5. ...
EDP Sciences2013Membership, binarity, and rotation of red dwarfs in the nearby open cluster Coma Berenices (Melotte 111)
Context. Although several attempts have been made to identify solar-type members on the main sequence of the nearby open cluster Coma Berenices (Mel 111), the population of the lower main sequence is still poorly known. ...
2008Flares from a candidate Galactic magnetar suggest a missing link to dim isolated neutron stars
Magnetars(1) are young neutron stars with very strong magnetic fields of the order of 10(14)-10(15) G. They are detected in our Galaxy either as soft gamma-ray repeaters or anomalous X-ray pulsars. Soft gamma-ray repeaters are a rare type of gamma-ray tran ...
2008Gravitational lenses
The Hubble constant H0 is one of the most important parameters in cosmology, as it encodes the age of the Universe and is necessary for any distance determination at a cosmological scale. It is, however, only poorly constrained by traditional methods. The ...
