UGC 7639: a Dwarf Galaxy in the Canes Venatici I Cloud
L. M. Buson, D. Bettoni, P. Mazzei +1
We want to get insight into the nature, i.e. the formation mechanism and the evolution, of UGC 7639, a dwarf galaxy in the Canes Venatici I Cloud (CVnIC). We used archival GALEX (F…
Dissecting Kinematics and Stellar Populations of Counter-Rotating Galaxies with 2-Dimensional Spectroscopy
L. Coccato, L. Morelli, A. Pizzella +3
We present a spectral decomposition technique and its applications to a sample of galaxies hosting large-scale counter-rotating stellar disks. Our spectral decomposition technique…
Unusual PAH Emission in Nearby Early-Type Galaxies: A Signature of an Intermediate Age Stellar Population?
O. Vega, A. Bressan, P. Panuzzo +6
We present the analysis of Spitzer-IRS spectra of four early-type galaxies, NGC 1297, NGC 5044, NGC 6868, and NGC 7079, all classified as LINERs in the optical bands. Their IRS spe…
The ultraviolet flare at the center of the elliptical galaxy NGC 4278
A. Cardullo, E. M. Corsini, A. Beifiori +5
A large fraction of otherwise normal galaxies shows a weak nuclear activity. One of the signatures of the low-luminosity active galactic nuclei (LLAGNs) is the ultraviolet variabil…
The role of the synchrotron component in the mid infrared spectrum of M 87
L. Buson, A. Bressan, P. Panuzzo +7
We study in detail the mid-infrared Spitzer-IRS spectrum of M 87 in the range 5 to 20 micron. Thanks to the high sensitivity of our Spitzer-IRS spectra we can disentangle the stell…
The Cuspy LINER Nucleus of the S0/a Galaxy NGC 2681
Michele Cappellari, Francesco Bertola, David Burstein +3
The nucleus of the bulge-dominated, multiply-barred S0/a galaxy NGC 2681 is studied in detail, using high resolution Hubble Space Telescope FOC and NICMOS imaging and FOS spectrosc…
