The AGORA High-resolution Galaxy Simulations Comparison Project. V. Satellite Galaxy Populations in a Cosmological Zoom-in Simulation of a Milky Way-Mass Halo
Yves Revaz, Loïc Hausammann, Alessandro Lupi
We analyze and compare the satellite halo populations at z similar to 2 in the high-resolution cosmological zoom-in simulations of a 1012 M circle dot target halo (z = 0 mass) carried out on eight widely used astrophysical simulation codes (Art-I, Enzo, Ra ...
Bristol2024Precision luminosity measurement at hadron colliders
This thesis links two realms of particle accelerator dynamics and precision particle physics. The achievement of precise luminosity measurement at hadron colliders is enabled with dedicated luminometers. For the Run 3 period, the luminometer upgrade was pl ...
EPFL2024Gaia Data Release 3 Summary of the variability processing and analysis
Context. Gaia has been in operations since 2014, and two full data releases (DR) have been delivered so far: DR1 in 2016 and DR2 in 2018. The third Gaia data release expands from the early data release (EDR3) in 2020, which contained the five-parameter ast ...
EDP SCIENCES S A2023Gaia Focused Product Release: Asteroid orbital solution: Properties and assessment
Stephan Morgenthaler, Shuangqing Liao
Context. We report the exploitation of a sample of Solar System observations based on data from the third Gaia Data Release (Gaia DR3) of nearly 157 000 asteroids. It extends the epoch astrometric solution over the time coverage planned for the Gaia DR4, w ...
Les Ulis Cedex A2023Vers une agriculture flottante: faire face à la diminution des ressources de la pêche dans les villages sur pilotis du Tonlé Sap (Cambodge)
Plus grand lac d’eau douce d’Asie du Sud-Est, le Tonlé Sap est une réserve de poissons vitale pour la population cambodgienne. Cependant, leur quantité diminue en raison des changements climatiques et de la construction massive de barrages le long du Mékon ...
2023Crowded No More: The Accuracy of the Hubble Constant Tested with High-resolution Observations of Cepheids by JWST
High-resolution James Webb Space Telescope (JWST) observations can test confusion-limited Hubble Space Telescope (HST) observations for a photometric bias that could affect extragalactic Cepheids and the determination of the Hubble constant. We present JWS ...
