Local and large-scale effects on the astrophysics of void galaxies
Monthly Notices of the Royal Astronomical Society, 2023 ABSTRACT Galaxies in cosmic voids have been reported with properties related to a delayed evolution compared to the rest of the Universe. These characteristics reflect the interaction of galaxies with the environment. However, it is not clear the degree of influence of the large-scale structure on the properties of void galaxies or if ...

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 ...

Tales within Tales and Cutoffs within Cutoffs: What Sets the Mass Scale for Galaxies? [PDF]
, 2001 Please answer ``yes'' or ``no'': 1. Does the mass function for clusters of galaxies cut off exponentially? 2. Does the luminosity function for galaxies cut off exponentially? 3. Is the dependence of virial velocity on galaxy luminosity a power law?

Observed Properties of Dark Matter on Small Spatial Scales [PDF]
, 2007 The nature of dark matter is one of the outstanding questions of astrophysics. The internal motions of member stars reveal that the lowest luminosity galaxies in the Local Group are the most dark-matter dominated.

Cold fronts: probes of plasma astrophysics in galaxy clusters [PDF]
Journal of Plasma Physics, 2016 The most massive baryonic component of galaxy clusters is the ‘intracluster medium’ (ICM), a diffuse, hot, weakly magnetized plasma that is most easily observed in the X-ray band. Despite being observed for decades, the macroscopic transport properties of the ICM are still not well constrained.
