Exploring the Evolution of a Dwarf Spheroidal Galaxy with SPH Simulations. II. AGN Feedback
The Astrophysical JournalWe investigate active galactic nucleus (AGN) feedback from an intermediate-mass black hole at the center of a dwarf spheroidal galaxy, by performing isolated galaxy simulations using a modified version of the GADGET-3 code. We consider Leo II (PGC 34176)

Variable Stars in Dwarf Spheroidal Galaxies [PDF]
International Astronomical Union Colloquium, 1973 Interest in dwarf spheroidal galaxies is motivated by a number of reasons; an important one on the occasion of this colloquium is the abundance of variable stars. The theory of stellar evolution and stellar pulsations is now able to predict from theoretical considerations characteristic properties of variable stars in the colour-magnitude diagram (Iben,

Properties of the Photometric Components of Lenticular Galaxies
Advances in Astronomy, Volume 2012, Issue 1, 2012., 2012 After almost one century since their definition, the origin of lenticular galaxies is still a matter of debate. Several formation processes have been proposed in order to explain the wide variety of their observational properties. These properties could indicate that the class of lenticulars is a family formed by galaxies with different formations and ...

Are Nuclear Star Clusters the Precursors of Massive Black Holes?
Advances in Astronomy, Volume 2012, Issue 1, 2012., 2012 We present new upper limits for black hole masses in extremely late type spiral galaxies. We confirm that this class of galaxies has black holes with masses less than 106M⊙, if any. We also derive new upper limits for nuclear star cluster masses in massive galaxies with previously determined black hole masses.

, 2019 In this work we use structural properties of Milky Way's outer halo ($R_G > 25\,\mathrm{kpc}$) satellites (dwarf spheroidal galaxies, ultra-faint dwarf galaxies and globular clusters) derived from deep, wide-field and homogeneous data, to present ...

Updated Bounds on Axion‐Like Particle Dark Matter with the Optical MUSE‐Faint Survey
Annalen der Physik, Volume 536, Issue 1, January 2024.This study presents bounds on the axion‐like particle (ALP) to two‐photon coupling in the mass range $2.65‐5.27$ eV. The signal from ALP decay are sought in the Multi Unit Spectroscopic Explorer (MUSE) observations of five dwarf spheroidal galaxies, under the assumption that ALPs make up the whole dark matter.
