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 ...

A comparison of metal and Ly-α absorption in galactic haloes [PDF]
Serbian Astronomical Journal, 1998 The metallicity structure of galactic haloes is one of the major unknowns in modern galactic astrophysics and observational cosmology. Hereby we outline a very simple method for obtaining at least a crude picture of gas abundances, based on ...

Counter-rotating black holes from FRII lifetimes
Frontiers in Astronomy and Space Sciences, 2023 Estimates suggest that while FRII jets appear to have lifetimes constrained to hundreds of millions of years, radio galaxies with FRI jets appear to be longer lived.

Multi-Frequency Study of the SZ Effect in Cosmic Structures
Acta Polytechnica CTU Proceedings, 2014 The Sunyaev-Zel’dovich effect (SZE) is a relevant probe for cosmology and astrophysics. A multi-frequency approach to study the SZE in cosmic structures turns out to be crucial in the use of this probe for astrophysics and cosmology.
