Uncovering the origin of complex velocity distributions in edge-on disc galaxies

Sophie Townson, Marie Martig, Robert J. J. Grand +3

Stellar line-of-sight velocity distributions are a powerful tool for studying galaxy kinematics and formation history, with multiple-peaked LOSVDs often indicating the presence of…

The Neutral Atomic Hydrogen in the solar neighborhood (NeAtHood) project I. Ghost in the shell: Neutral atomic hydrogen in the extended Orion nebula

J. D. Soler, H. Beuther, S. C. O. Glover +15

The Orion Nebula is the nearest site of ongoing and recent high-mass star formation. It is a unique laboratory for studying the mass, energy, and momentum input from high-mass star…

Semiresolved Stellar Populations as Distance Indicators

Ignacio Martín-Navarro, Patricia Iglesias Navarro, Francesco La Barbera +13

Galaxy distances are central to our understanding of the Universe. Despite the success of existing approaches, independent and complementary methods remain valuable for testing sys…

The GECKOS survey: Assembly history of the lenticular galaxy NGC 3957

Yuchen Ding, Marie Martig, Ling Zhu +24

We analyse the assembly history of the edge-on lenticular galaxy NGC 3957 using deep integral-field spectroscopic MUSE data from the GECKOS survey. By applying a dust-corrected Mul…

The influence of feedback on the baryonic content of haloes in the COLIBRE simulations

Jonathan J. Davies, Joop Schaye, Filip Huško +7

We present predictions for the relation between the halo gas mass fraction and halo mass, , from the COLIBRE cosmological simulations of galaxy formation…

A Long Period Stellar-Mass Black Hole Binary in Centauri

Matthew Whitaker, Evan Kerr, Anil Seth +16

Modern simulations of stellar dynamics in globular clusters peg a dominant role for stellar-mass black holes, but direct evidence for black holes in clusters remains limited. We pr…
