Could the Fermi-LAT detect gamma-rays from dark matter annihilation in the dwarf galaxies of the Local Group?
L. Pieri, A. Pizzella, E. M. Corsini +2
The detection of gamma-rays from dark matter (DM) annihilation is among the scientific goals of the Fermi Large Area Telescope (formerly known as GLAST) and Cherenkov telescopes. I…
Dark matter scaling relations and the assembly epoch of Coma early-type galaxies
J. Thomas, R. P. Saglia, R. Bender +5
Axisymmetric, orbit-based dynamical models are used to derive dark matter scaling relations for Coma early-type galaxies. From faint to bright galaxies halo core-radii and asymptot…
The bar pattern speed of NGC 4431
E. M. Corsini, J. A. L. Aguerri, Victor P. Debattista +3
We present surface photometry and stellar kinematics of NGC 4431, a barred dwarf galaxy in the Virgo cluster undergoing a tidal interaction with one of its neighbors, NGC 4436. We…
NGC5719/13: interacting spirals forming a counter-rotating stellar disc
D. Vergani, A. Pizzella, E. M. Corsini +4
(Context) When a galaxy acquires material from the outside, it is likely that the resulting angular momentum of the accreted material is decoupled from that of the pre-existing gal…
Upper limits on the mass of supermassive black holes from HST/STIS archival data
E. M. Corsini, A. Beifiori, E. Dalla Bonta` +4
The growth of supermassive black holes (SBHs) appears to be closely linked with the formation of spheroids. There is a pressing need to acquire better statistics on SBH masses, sin…
The relation between circular velocity and central velocity dispersion in low surface brightness galaxies
E. M. Corsini, A. Pizzella, E. Dalla Bonta` +3
We analyzed a sample of high and low surface brightness (HSB and LSB) disc galaxies and elliptical galaxies to investigate the correlation between the circular velocity (Vc) and th…
NGC 7679: an anomalous, composite Seyfert 1 galaxy whose, X-ray luminous AGN vanishes at optical wavelengths
L. M. Buson, M. Cappellari, E. M. Corsini +3
Morphological disturbances and gas kinematics of the SB0 galaxy NGC 7679=Arp 216 are investigated to get clues to the history of this highly composite object, where AGN and starbur…
Measurement of fast bars in a sample of early-type barred galaxies
J. A. L. Aguerri, V. P. Debattista, E. M. Corsini
We present surface photometry and stellar kinematics of a sample of 5 SB0 galaxies: ESO 139-G009, IC 874, NGC 1308, NGC 1440 and NGC 3412. We measured their bar pattern speed using…
The Orthogonal Gaseous Kinematical Decoupling in the Sa Spiral NGC 2855
E. M. Corsini, A. Pizzella, F. Bertola
We present major and minor-axis kinematics of stars and ionized gas as well as narrow and broad-band surface photometry of the Sa spiral NGC 2855. In the nuclear regions of this un…
Kinematic properties of gas and stars in 20 disc galaxies
J. C. Vega Beltran, A. Pizzella, E. M. Corsini +4
Ionized gas and stellar kinematical parameters have been measured along the major axis of 20 nearby disc galaxies. We discuss the properties of each sample galaxy distinguishing be…
Modelling gaseous and stellar kinematics in the disc galaxies NGC 772, NGC 3898, and NGC 7782
E. Pignatelli, E. M. Corsini, J. C. Vega Beltran +7
We present V-band surface photometry and major-axis kinematics of stars and ionized gas of three early-type spiral galaxies, namely NGC 772, NGC 3898 and NGC 7782. For each galaxy…
Disk Galaxies and Galaxy Disks
J. G. Funes S. J, E. M. Corsini
The conference Galaxy Disks and Disk Galaxies, sponsored by the Vatican Observatory, was held in June 12-16, 2000 at the Pontifical Gregorian University, in Rome (Italy). The meeti…
Dark matter in early-type spiral galaxies: the case of NGC 2179 and of NGC 2775
E. M. Corsini, A. Pizzella, M. Sarzi +6
We present stellar and ionized-gas velocity curves and velocity dispersion profiles for the Sa galaxies NGC 2179 and NGC 2775. Using their luminosity profiles and modeling both the…
Mixed Early and Late-Type Properties in the Bar of NGC 6221: Evidence for Evolution along the Hubble Sequence?
J. C. Vega Beltran, W. W. Zeilinger, P. Amico +5
Rotation curves and velocity dispersion profiles are presented for both the stellar and gaseous components along five different position angles (P.A.=5, 50, 95, 125 and 155 degrees…
