From light to baryonic mass: the effect of the stellar mass-to-light ratio on the Baryonic Tully-Fisher relation
Anastasia A. Ponomareva, Marc A. W. Verheijen, Emmanouil Papastergis +2
In this paper we investigate the statistical properties of the Baryonic Tully-Fisher relation (BTFr) for a sample of 32 galaxies with accurate distances based on Cepheids and/or TR…
HI in Virgo's "Red and Dead" Dwarf Ellipticals - A Tidal Tail and Central Star Formation
Gregory Hallenbeck, Rebecca Koopmann, Riccardo Giovanelli +4
We investigate a sample of 3 dwarf elliptical galaxies in the Virgo Cluster which have significant reservoirs of HI. We present deep optical imaging (from CFHT and KPNO), HI spectr…
The HI content of isolated ultra-diffuse galaxies: A sign of multiple formation mechanisms?
E. Papastergis, E. A. K. Adams, A. J. Romanowsky
We report on the results of radio observations in the 21 cm emission line of atomic hydrogen (HI) of four relatively isolated ultra-diffuse galaxies (UDGs): DGSAT I, R-127-1, M-161…
A new astrophysical solution to the Too Big To Fail problem - Insights from the MoRIA simulations
Robbert Verbeke, Emmanouil Papastergis, Anastasia A. Ponomareva +2
We test whether advanced galaxy models and analysis techniques of simulations can alleviate the Too Big To Fail problem (TBTF) for late-type galaxies, which states that isolated dw…
How to Reconcile the Observed Velocity Function of Galaxies with Theory
Alyson M. Brooks, Emmanouil Papastergis, Charlotte R. Christensen +4
Within a Lambda Cold Dark Matter (LCDM) scenario, we use high resolution cosmological simulations spanning over four orders of magnitude in galaxy mass to understand the deficit of…
