We present cosmological results from the measurement of clustering of galaxy, quasar and Lyman-$\alpha$ forest tracers from the first year of observations with the Dark Energy Spectroscopic Instrument (DESI Data Release 1). We adopt the full-shape (F

FLAMINGO: combining kinetic SZ effect and galaxy-galaxy lensing measurements to gauge the impact of feedback on large-scale structure

Autor: McCarthy, Ian G., Amon, Alexandra, Schaye, Joop, Schaan, Emmanuel, Angulo, Raul E., Salcido, Jaime, Schaller, Matthieu, Bigwood, Leah, Elbers, Willem, Kugel, Roi, Helly, John C., Moreno, Victor J. Forouhar, Frenk, Carlos S., McGibbon, Robert J., Ondaro-Mallea, Lurdes, van Daalen, Marcel P.

Energetic feedback processes associated with accreting supermassive black holes can expel gas from massive haloes and significantly alter various measures of clustering on ~Mpc scales, potentially biasing the values of cosmological parameters inferre

Galaxy Mass Modelling from Multi-Wavelength JWST Strong Lens Analysis: Dark Matter Substructure, Angular Mass Complexity, or Both?

Autor: Lange, Samuel C., Amvrosiadis, Aristeidis, Nightingale, James W., He, Qiuhan, Frenk, Carlos S., Robertson, Andrew, Cole, Shaun, Massey, Richard, Cao, Xiaoyue, Li, Ran, Wang, Kaihao

We analyze two galaxy-scale strong gravitational lenses, SPT0418-47 and SPT2147-50, using JWST NIRCam imaging across multiple filters. To account for angular complexity in the lens mass distribution, we introduce multipole perturbations with orders $

Constraints on the properties of $\nu$MSM dark matter using the satellite galaxies of the Milky Way

Autor: Newton, Oliver, Lovell, Mark R., Frenk, Carlos S., Jenkins, Adrian, Helly, John C., Cole, Shaun, Benson, Andrew J.

Low-mass galaxies provide a powerful tool with which to investigate departures from the standard cosmological paradigm in models that suppress the abundance of small dark matter structures. One of the simplest metrics that can be used to compare diff

Apocalypse When? No Certainty of a Milky Way -- Andromeda Collision

Autor: Sawala, Till, Delhomelle, Jehanne, Deason, Alis J., Frenk, Carlos S., Johansson, Peter H., Keitaanranta, Atte, Rawlings, Alexander, Wright, Ruby

It is commonly believed that our own Milky Way is on a collision course with the neighbouring Andromeda galaxy. As a result of their merger, predicted in around five billion years, the two large spiral galaxies that define the present Local Group wou
