A novel analysis of contamination in Lyman-break galaxy samples at : spatial correlation with intermediate-redshift galaxies at
Miftahul Hilmi, Nicha Leethochawalit, Michele Trenti +1
Potential contamination from low/intermediate-redshift galaxies, such as objects with a prominent Balmer break, affects the photometric selection of high-redshift galaxies through…
Detecting clusters and groups of galaxies populating the local Universe in large optical spectroscopic surveys
I. Marini, P. Popesso, K. Dolag +13
Wide-field cosmological surveys provide hundreds of thousands of spectroscopically confirmed galaxy groups and clusters, valuable for tracing baryonic matter distribution. However,…
WALLABY Pilot Survey: Gas-Rich Galaxy Scaling Relations from Marginally-Resolved Kinematic Models
N. Deg, N. Arora, K. Spekkens +21
We present the first set of galaxy scaling relations derived from kinematic models of the Widefield ASKAP L-band Legacy All-sky Blind surveY (WALLABY) pilot phase observations. Com…
Detection and Characterisation of Giant Planets with Gaia Astrometry
A. L. Wallace, A. R. Casey, A. G. A. Brown +1
Astrometric observations with Gaia are expected to play a valuable role in future exoplanet surveys. With current data from Gaia's third data release (DR3), we are sensitive to per…
AHKASH: a new Hybrid particle-in-cell code for simulations of astrophysical collisionless plasma
Radhika Achikanath Chirakkara, Christoph Federrath, Amit Seta
We introduce strophysical ybrid-inetic simulations with the code () -- a new Hybrid particle-in-cell (PIC) cod…
Galaxy assembly bias in the stellar-to-halo mass relation for red central galaxies from SDSS
Grecco A. Oyarzún, Jeremy L. Tinker, Kevin Bundy +2
We report evidence of galaxy assembly bias - the correlation between galaxy properties and biased secondary halo properties at fixed halo mass (M) - in the stellar-to-halo mass…
