gradients driven by IMF variation: Large impact on dynamical stellar mass estimates
M. Bernardi, R. K. Sheth, H. Dominguez-Sanchez +4
Within a galaxy the stellar mass-to-light ratio is not constant. Spatially resolved kinematics of nearby early-type galaxies suggest that allowing for a variable initial mass…
Revisiting the bulge-halo conspiracy II: Towards explaining its puzzling dependence on redshift
Francesco Shankar, Alessandro Sonnenfeld, Philip Grylls +8
We carry out a systematic investigation of the total mass density profile of massive (Mstar~3e11 Msun) early-type galaxies and its dependence on redshift, specifically in the range…
Improving galaxy morphologies for SDSS with Deep Learning
H. Domínguez Sánchez, M. Huertas-Company, M. Bernardi +2
We present a morphological catalogue for 670,000 galaxies in the Sloan Digital Sky Survey in two flavours: T-Type, related to the Hubble sequence, and Galaxy Zoo 2 (GZ2 here…
Stellar mass functions and implications for a variable IMF
M. Bernardi, R. K. Sheth, J. -L. Fischer +6
Spatially resolved kinematics of nearby galaxies has shown that the ratio of dynamical- to stellar population-based estimates of the mass of a galaxy () correlat…
The Fourteenth Data Release of the Sloan Digital Sky Survey: First Spectroscopic Data from the extended Baryon Oscillation Spectroscopic Survey and from the second phase of the Apache Point Observatory Galactic Evolution Experiment
Bela Abolfathi, D. S. Aguado, Gabriela Aguilar +344
The fourth generation of the Sloan Digital Sky Survey (SDSS-IV) has been in operation since July 2014. This paper describes the second data release from this phase, and the fourtee…
Radial Acceleration Relation between Baryons and Dark or Phantom Matter in the Super-critical Acceleration Regime of Nearly Spherical Galaxies
Kyu-Hyun Chae, Mariangela Bernardi, Ravi K. Sheth +1
The central regions of nearby elliptical galaxies are dominated by baryons (stars) and provide interesting laboratories for studying the radial acceleration relation (RAR). We carr…
Comparing PyMorph and SDSS photometry. II. The differences are more than semantics and are not dominated by intracluster light
M. Bernardi, J. -L. Fischer, R. K. Sheth +4
The Sloan Digital Sky Survey pipeline photometry underestimates the brightnesses of the most luminous galaxies. This is mainly because (i) the SDSS overestimates the sky background…
Revisiting the bulge-halo conspiracy I: Dependence on galaxy properties and halo mass
Francesco Shankar, Alessandro Sonnenfeld, Gary A. Mamon +9
We carry out a systematic investigation of the total mass density profile of massive (Mstar>2e11 Msun) early-type galaxies and its dependence on galactic properties and host halo m…
Comparing PyMorph and SDSS photometry. I. Background sky and model fitting effects
J. -L. Fischer, M. Bernardi, A. Meert
A number of recent estimates of the total luminosities of galaxies in the SDSS are significantly larger than those reported by the SDSS pipeline. This is because of a combination o…
Selection bias in dynamically-measured supermassive black hole samples: Scaling relations and correlations between residuals in semi-analytic galaxy formation models
Enrico Barausse, Francesco Shankar, Mariangela Bernardi +2
Recent work has confirmed that the masses of supermassive black holes, estimated from scaling relations with global properties such as the stellar masses of their host galaxies, ma…
Selection bias in dynamically-measured super-massive black hole samples: dynamical masses and dependence on Sérsic index
Francesco Shankar, Mariangela Bernardi, Ravi K. Sheth
We extend the comparison between the set of local galaxies having dynamically measured black holes with galaxies in the Sloan Digital Sky Survey (SDSS). We first show that the most…
