Angular momentum of galaxies and their local analogues with adaptive optics
Sarah M. Sweet, Deanne B. Fisher, Giulia Savorgnan +9
We present stellar specific angular momentum measurements of two galaxies in the KGES sample and 12 DYNAMO analogues of high-redshift galaxies. We com…
The UVES Spectral Quasar Absorption Database (SQUAD) Data Release 1: The first 10 million seconds
Michael T. Murphy, Glenn G. Kacprzak, Giulia A. D. Savorgnan +1
We present the first data release (DR1) of the UVES Spectral Quasar Absorption Database (SQUAD), comprising 467 fully reduced, continuum-fitted high-resolution quasar spectra from…
The SLUGGS Survey: stellar masses and effective radii of early-type galaxies from Spitzer Space Telescope 3.6m imaging
Duncan A. Forbes, Luciana Sinpetru, Giulia Savorgnan +3
Galaxy starlight at 3.6m is an excellent tracer of stellar mass. Here we use the latest 3.6m imaging from the Spitzer Space Telescope to measure the total stellar mass and ef…
Disky elliptical galaxies and the allegedly over-massive black hole in the compact massive `ES' galaxy NGC 1271
Alister W. Graham, Bogdan C. Ciambur, Giulia A. D. Savorgnan
While spiral and lenticular galaxies have large-scale disks extending beyond their bulges, and most local early-type galaxies with 10^{10} < M_*/M_Sun < 2x10^{11} contain a disk (e…
Supermassive black holes and their host spheroids III. The correlation
Giulia A. D. Savorgnan
The Sérsic model is the best approximation known to date for describing the light distribution of stellar spheroidal and disk components, with the Sérsic index provid…
Selection bias in dynamically-measured super-massive black hole samples: its consequences and the quest for the most fundamental relation
Francesco Shankar, Mariangela Bernardi, Ravi K. Sheth +7
We compare the set of local galaxies having dynamically measured black holes with a large, unbiased sample of galaxies extracted from the Sloan Digital Sky Survey. We confirm earli…
A normal supermassive black hole in NGC 1277
Alister W. Graham, Mark Durré, Giulia A. D. Savorgnan +5
The identification of galaxies with `overly massive' black holes requires two measurements: a black hole mass (M_bh) and a host spheroid mass (M_sph,*). Here we provide our measure…
Explaining the reportedly over-massive black holes in early-type galaxies with intermediate-scale discs
Giulia A. D. Savorgnan, Alister W. Graham
The classification "early-type" galaxy includes both elliptically- and lenticular-shaped galaxies. Theoretically, the spheroid-to-disc flux ratio of an early-type galaxy can assume…
Supermassive black holes and their host spheroids II. The red and blue sequence in the diagram
Giulia A. D. Savorgnan, Alister W. Graham, Alessandro Marconi +1
In our first paper, we performed a detailed (i.e. bulge, disks, bars, spiral arms, rings, halo, nucleus, etc.) decomposition of 66 galaxies, with directly measured black hole masse…
Supermassive black holes and their host spheroids I. Disassembling galaxies
Giulia A. D. Savorgnan, Alister W. Graham
Several recent studies have performed galaxy decompositions to investigate correlations between the black hole mass and various properties of the host spheroid, but they have not c…
The role of bars in quenching star formation from z = 3 to the present epoch. Halpha3: an Halpha imaging survey of HI selected galaxies from ALFALFA, VI
G. Gavazzi, G. Consolandi, M. Dotti +10
A growing body of evidence indicates that the star formation rate per unit stellar mass (sSFR) decreases with increasing mass in normal "main-sequence" star forming galaxies. Many…
Halpha3: an Halpha imaging survey of HI selected galaxies from ALFALFA. V: The Coma Supercluster survey completion
Giuseppe Gavazzi, Guido Consolandi, Elisa Viscardi +8
Neutral hydrogen represents the major observable baryonic constituent of galaxies that fuels the formation of stars through the transformation in molecular hydrogen. The emission o…
Hiding in plain sight: An abundance of compact massive spheroids in the local Universe
Alister W. Graham, Bililign T. Dullo, Giulia A. D. Savorgnan
It has been widely remarked that compact, massive, elliptical-like galaxies are abundant at high redshifts but exceedingly rare in the Universe today, implying significant evolutio…
Overmassive black holes in the diagram do not belong to over (dry) merged galaxies
Giulia A. D. Savorgnan, Alister W. Graham
Semi-analytical models in a CDM cosmology have predicted the presence of outlying, "overmassive" black holes at the high-mass end of the (black hole mass -- galaxy velocity disp…
Red-channel (6000-8000 Å) nuclear spectra of 376 local galaxies
Giuseppe Gavazzi, Guido Consolandi, Massimo Dotti +4
We obtained long-slit optical spectra of the nuclear regions of 376 galaxies in the local Universe using the 1.5m Cassini telescope of Bologna Observatory. Of these spectra, 164 we…
The supermassive black hole mass - Sérsic index relations for bulges and elliptical galaxies
Giulia Savorgnan, Alister W. Graham, Alessandro Marconi +4
Scaling relations between supermassive black hole mass, M_BH, and host galaxy properties are a powerful instrument for studying their coevolution. A complete picture involving all…
Halpha3: an Halpha imaging survey of HI selected galaxies from ALFALFA. III. Nurture shapes up the Hubble sequence in the Great Wall
Giuseppe Gavazzi, Giulia Savorgnan, Matteo Fossati +7
We present the analysis of Halpha3, an Halpha imaging survey of galaxies selected from the HI ALFALFA Survey in the Coma Supercluster. By using the Halpha line as a tracer of the "…

Giuseppe Gavazzi, Giulia Savorgnan, Mattia Fumagalli
To investigate the dependence of the occurrence of active galactic nuclei (AGNs) on local galaxy density, we study the nuclear properties of ~5000 galaxies in the Coma Supercluster…
