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 ...

Galaxy Evolution with Manifold Learning [PDF]
EntropyMatter in the early Universe was nearly uniform, and galaxies emerged through the gravitational growth of small primordial density fluctuations. Astrophysics has been trying to unveil the complex physical phenomena that have caused the formation and ...

A Walk through AGN Country—For the Somewhat Initiated!
Galaxies, 2023 Key issues in AGN and galaxy formation are discussed. Very successful Unified Models explain much of the variety of AGN with orientation effects; the ingredients are shadowing by a dusty “torus” and relativistic beaming.

Cosmology with One Galaxy? The ASTRID Model and Robustness
The Astrophysical Journal, 2023 Recent work has pointed out the potential existence of a tight relation between the cosmological parameter Ω _m , at fixed Ω _b , and the properties of individual galaxies in state-of-the-art cosmological hydrodynamic simulations.

The Sunyaev-Zeldovich effect from clusters of galaxies [PDF]
EPJ Web of Conferences, 2020 In this paper, we recall the basics of the the Sunyaev-Zeldovich effect from groups and clusters of galaxies. We review the transformational results from SZ surveys in the past decade, that have led to the detection of new clusters of galaxies from the ...

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 ...
