The slow evolution of dark matter halos from cusp to core naturally produces extended stellar core-like distributions
Jorge Sanchez Almeida, Angel R. Plastino, Ignacio Trujillo
Motivated by the observation of extended stellar cores in dark matter (DM) dominated dwarf galaxies, this study investigates a simple mechanism by which stellar cores can form as a…
Application of the Eddington inversion method to constrain the dark matter halo of galaxies using only observed surface brightness profiles
Jorge Sanchez Almeida, Angel R. Plastino, Ignacio Trujillo
*** Context: The halos of low-mass galaxies may allow us to constrain the nature of dark matter (DM), but the kinematic measurements to diagnose the required properties are technic…
Deep HST imaging favors the bulgeless edge-on galaxy explanation for the hypothetical stellar wake created by a runaway supermassive black hole
Mireia Montes, Jorge Sánchez Almeida, Ignacio Trujillo
A long linear structure recently discovered could be the stellar wake produced by the passage of a runaway supermassive black hole (SMBH) or, alternatively, a bulgeless edge-on gal…
Can cuspy dark matter dominated halos hold cored stellar mass distributions?
Jorge Sanchez Almeida, Angel R. Plastino, Ignacio Trujillo
According to the current concordance cosmological model, the dark matter (DM) particles are collision-less and produce self-gravitating structures with a central cusp which, genera…
Super-massive black hole wake or bulgeless edge-on galaxy?
Jorge Sanchez Almeida, Mireia Montes, Ignacio Trujillo
van Dokkum et al. (2023) reported the serendipitous discovery of a thin linear object interpreted as the trail of star-forming regions left behind by a runaway supermassive black h…
Physically motivated fit to mass surface density profiles observed in galaxies
J. Sanchez Almeida, I. Trujillo, A. R. Plastino
Polytropes have gained renewed interest because they account for several seemingly-disconnected observational properties of galaxies. Here we study if polytropes are also able to e…
