Galaxy Formation with BECDM -- II. Cosmic Filaments and First Galaxies
Philip Mocz, Anastasia Fialkov, Mark Vogelsberger +11
Bose-Einstein Condensate Dark Matter (BECDM; also known as Fuzzy Dark Matter) is motivated by fundamental physics and has recently received significant attention as a serious alter…
Core mass -- halo mass relation of bosonic and fermionic dark matter halos harbouring a supermassive black hole
Pierre-Henri Chavanis
We study the core mass -- halo mass relation of bosonic dark matter halos, in the form of self-gravitating Bose-Einstein condensates, harbouring a supermassive black hole. We use t…
First star-forming structures in fuzzy cosmic filaments
Philip Mocz, Anastasia Fialkov, Mark Vogelsberger +10
In hierarchical models of structure formation, the first galaxies form in low-mass dark matter potential wells, probing the behavior of dark matter on kiloparsec (kpc) scales. Even…
Mass-radius relation of self-gravitating Bose-Einstein condensates with a central black hole
Pierre-Henri Chavanis
We determine the mass-radius relation of self-gravitating Bose-Einstein condensates with an attractive external potential created by a central mass. Following our previous w…
Implosion-explosion in supernovae
Pierre-Henri Chavanis, Bruno Denet, Martine Le Berre +1
Supernovae explosions of massive stars are nowadays believed to result from a two-step process, with an initial gravitational core collapse followed by an expansion of matter after…
Supernova implosion-explosion in the light of catastrophe theory
Pierre-Henri Chavanis, Bruno Denet, Martine Le Berre +1
The present understanding of supernova explosion of massive stars as a two-step process, with an initial gravitational collapse toward the center of the star followed by an expansi…
Statistical mechanics of self-gravitating systems in general relativity: II. The classical Boltzmann gas
Pierre-Henri Chavanis
We study the statistical mechanics of classical self-gravitating systems confined within a box of radius in general relativity. It has been found that the caloric curve $T_{\in…
Statistical mechanics of self-gravitating systems in general relativity: I. The quantum Fermi gas
Pierre-Henri Chavanis
We develop a general formalism to determine the statistical equilibrium states of self-gravitating systems in general relativity and complete previous works on the subject. Our res…
Caloric curves of classical self-gravitating systems in general relativity
Giuseppe Alberti, Pierre-Henri Chavanis
We determine the caloric curves of classical self-gravitating systems at statistical equilibrium in general relativity. In the classical limit, the caloric curves of a self-gravita…
Gravitational phase transitions and instabilities of self-gravitating fermions in general relativity
Pierre-Henri Chavanis, Giuseppe Alberti
We discuss the occurrence of gravitational phase transitions and instabilities in a gas of self-gravitating fermions within the framework of general relativity. In the classical (n…
Kinetic theory of homogeneous long-range interacting systems sourced by effects
Jean-Baptiste Fouvry, Ben Bar-Or, Pierre-Henri Chavanis
The long-term dynamics of long-range interacting -body systems can generically be described by the Balescu-Lenard kinetic equation. However, for homogeneous systems, this…
Derivation of the core mass -- halo mass relation of fermionic and bosonic dark matter halos from an effective thermodynamical model
Pierre-Henri Chavanis
We consider the possibility that dark matter halos are made of quantum particles such as fermions or bosons in the form of Bose-Einstein condensates. In that case, they generically…
Generalized Euler, Smoluchowski and Schrödinger equations admitting self-similar solutions with a Tsallis invariant profile
Pierre-Henri Chavanis
The damped isothermal Euler equations, the Smoluchowski equation and the damped logarithmic Schrödinger equation with a harmonic potential admit stationary and self-similar solutio…
Gravitational phase transition of self-gravitating systems of fermions in General Relativity
Giuseppe Alberti, Pierre-Henri Chavanis
The Thomas-Fermi model is extended at finite temperature, to describe the gravitational phase transition occurring in massive fermionic systems in a general-relativistic framework.…
