Fermionic Dark Matter: Physics, Astrophysics, and Cosmology [PDF]
Universe, 2023 The nature of dark matter (DM) is one of the most relevant questions in modern astrophysics. We present a brief overview of recent results that inquire into the possible fermionic quantum nature of the DM particles, focusing mainly on the interconnection

Global HI profiles of spiral galaxies [PDF]
, 1995 In this paper we present short HI synthesis observations of 57 galaxies without HI information in the RC3. These are a by-product of a large survey with the WSRT of the neutral hydrogen gas in spiral and irregular galaxies.

Astrophysical probes of the Vainshtein mechanism: Stars and galaxies [PDF]
Physical Review D, 2015 Ghost-free theories beyond the Horndeski class exhibit a partial breaking of the Vainshtein mechanism inside non-relativistic sources of finite extent. We exploit this breaking to identify new and novel astrophysical probes of these theories. Non-relativistic objects feel a gravitational force that is weaker than that predicted by general relativity ...

Asteroseismic modelling of fast rotators and its opportunities for astrophysics [PDF]
Astronomy & Astrophysics, 2023 Rotation matters for the life of a star. It causes a multitude of dynamical phenomena in the stellar interior during a star’s evolution, and its effects accumulate until the star dies.

The stellar mass function and star formation rate-stellar mass relation of galaxies at z ~ 4 - 7 [PDF]
, 2013 We investigate the evolution of the star formation rate-stellar mass relation (SFR-M*) and Galaxy Stellar Mass Function (GSMF) of z ~ 4-7 galaxies, using cosmological simulations run with the smoothed particle hydrodynamics code P-GADGET3(XXL).

Templates for Fitting Photometry of Ultra-high-redshift Galaxies [PDF]
Astrophysical Journal Letters, 2022 Recent data from the James Webb Space Telescope allow a first glimpse of galaxies at z ≳ 11. The most successful tool for identifying ultra-high-redshift candidates and inferring their properties is photometric template fitting.

The impact of baryonic processes on the two-point correlation functions of galaxies, subhaloes and matter [PDF]
, 2013 The observed clustering of galaxies and the cross-correlation of galaxies and mass provide important constraints on both cosmology and models of galaxy formation.
