The impact of superradiance on the spin evolution of variably accreting massive black holes
Adithya Nandakumar, Ricarda S. Beckmann, Vid Irsic
This paper explores how time-varying increases in mass accretion onto rapidly spinning black holes influence their long-term spin evolution when affected by superradiance - a proce…
Small-scale Lyman alpha forest cosmology with PRIYA: Constraints from XQ100 and KODIAQ-SQUAD one-dimensional flux power spectra
Ming-Feng Ho, Mahdi Qezlou, Simeon Bird +4
We present a new cosmological analysis of the small-scale Lyman alpha forest 1D flux power spectrum (P1D) using high-resolution quasar spectra from XQ100 and KODIAQ-SQUAD, interpre…
An improved model for the effect of correlated Si-III absorption on the one-dimensional Lyman- forest power spectrum
Ke Ma, James S. Bolton, Vid Irsic +2
We present an analysis of Si III absorption and its effect on the 1D Ly forest power spectrum using the Sherwood-Relics hydrodynamical simulation suite. In addition to oscillati…
The CosmoVerse White Paper: Addressing observational tensions in cosmology with systematics and fundamental physics
Eleonora Di Valentino, Jackson Levi Said, Adam Riess +533
The standard model of cosmology has provided a good phenomenological description of a wide range of observations both at astrophysical and cosmological scales for several decades.…
The case for large-scale AGN feedback in galaxy formation simulations: insights from XFABLE
Leah Bigwood, Martin A. Bourne, Vid Irsic +2
While cosmological simulations of galaxy formation have reached maturity, able to reproduce many fundamental galaxy and halo properties, no consensus has yet been reached on the im…
Constraints on Primordial Magnetic Fields from the Lyman-α forest
Mak Pavičević, Vid Iršič, Matteo Viel +5
We present the first constraints on primordial magnetic fields from the Lyman- forest using full cosmological hydrodynamic simulations. At the scales and redshifts probed by the…
