The carbon-rich type Ic SN 2007gr: the photospheric phase
S. Valenti, N. Elias-Rosa, S. Taubenberger +20
The first two months of spectroscopic and photometric monitoring of the nearby type Ic SN 2007gr are presented. The very early discovery (less than 5 days after the explosion) and…
New photometric and spectroscopic observations of the Seyfert galaxy Mrk 315
S. Ciroi, V. L. Afanasiev, A. V. Moiseev +5
We present new important results about the intermediate-type Seyfert galaxy Mrk 315, recently observed through optical imaging and integral-field spectroscopy. Broad-band images we…
Stellar velocity dispersion in NLS1 galaxies
V. Botte, S. Ciroi, F. Di Mille +2
Several authors recently explored the Black-Hole mass (M_BH) vs. stellar velocity dispersion (sigma_*) relationship for Narrow Line Seyfert 1 galaxies (NLS1s). Their results are mo…
Exploring NLS1 through the physical properties of their hosts
V. Botte, S. Ciroi, P. Rafanelli +1
In this work we aim at addressing the still open question about the nature of Narrow-Line Seyfert 1 (NLS1) galaxies: are they really active nuclei with lower mass Black-Holes (BHs)…
