A Unified Halo Mass Function Across Dark Matter Models from High-Resolution Multi-Scale Simulations

Andrew J. Benson, Ethan O. Nadler, Xiaolong Du +1

We measure the dark matter halo mass function, with backsplash halos removed, from a wide range of cosmological-box and zoom-in simulations. These include the MultiDark Planck boxe…

The ANDICAM-SOFI Near-infrared and Optical type Ia Supernova (ASNOS) sample: Description and data release

Kim Phan, Lluís Galbany, Tomás E. Müller-Bravo +13

Type Ia supernovae (SNe Ia) provide the most robust means of measuring extragalactic distances. While most of the effort has focused on increasing the number of SNe Ia observed in…

Constraining Cosmology with Double-source-plane Strong Gravitational Lenses from the AGEL Survey

Duncan J. Bowden, Nandini Sahu, Anowar J. Shajib +17

Double-source-plane strong gravitational lenses (DSPLs), with two sources at different redshifts, are independent cosmological probes of the dark energy equation of state parameter…

The THESAN project: environmental drivers of Local Group reionization

Yu Zhao, Aaron Smith, Rahul Kannan +5

The timing of cosmic reionization across Local Group (LG) analogues provides insights into their early histories and surrounding large-scale structure. Using the radiation-hydrodyn…

Interacting dark energy constraints from the full-shape analyses of BOSS DR12 and DES Year 3 measurements

M. Tsedrik, S. Lee, K. Markovic +8

Dark Scattering (DS) is an interacting dark energy model characterised by pure momentum exchange between dark energy and dark matter. It is phenomenologically interesting because i…

Elevated UV luminosity density at Cosmic Dawn explained by non-evolving, weakly mass-dependent star formation efficiency

Robert Feldmann, Michael Boylan-Kolchin, James S. Bullock +11

Recent observations with the James Webb Space Telescope (JWST) have uncovered unexpectedly high cosmic star formation activity in the early Universe, mere hundreds of millions of y…
