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…

SDSSJ143244.91+301435.3: a link between radio-loud narrow-line Seyfert 1 galaxies and compact steep-spectrum radio sources?

A. Caccianiga, S. Antón, L. Ballo +12

We present SDSSJ143244.91+301435.3, a new case of radio-loud narrow line Seyfert 1 (RL NLS1) with a relatively high radio power (P1.4GHz=2.1x10^25 W Hz^-1) and large radioloudness…

The optical-UV spectral energy distribution of the unabsorbed AGN population in the XMM-Newton Bright Serendipitous Survey

E. Marchese, R. Della Ceca, A. Caccianiga +3

Active galactic nuclei (AGN) emit radiation over a wide range of wavelengths, with a peak of emission in the far-UV region of the electromagnetic spectrum, a spectral region that i…

Studying the relationship between X-ray emission and accretion in AGNs using the XMM-Newton Bright Serendipitous Survey

R. Fanali, A. Caccianiga, P. Severgnini +5

We study the link between the X-ray emission in radio-quiet AGNs and the accretion rate on the central Supermassive Black Hole using a statistically well-defined and representative…

X-ray selected Narrow-Line Seyfert 1 Galaxies

A. Caccianiga, P. Severgnini, R. Della Ceca +3

We present and discuss the properties of a complete and well defined sample of X-ray selected type 1 AGNs including 26 Narrow-Line Seyfert 1 and 129 Broad-Line Seyfert 1 galaxies d…

astro-ph.GA2015

Bar-formation as driver of gas inflows in isolated disc galaxies

R. Fanali, M. Dotti, D. Fiacconi +1

Stellar bars are a common feature in massive disc galaxies. On a theoretical ground, the response of gas to a bar is generally thought to cause nuclear starbursts and, possibly, AG…

Black-hole masses of type 1 AGN in the XMM-Newton bright serendipitous survey

A. Caccianiga, R. Fanali, P. Severgnini +3

We derive masses of the central super-massive black hole (SMBH) and accretion rates for 154 type1 AGN belonging to a well-defined X-ray-selected sample, the XMM-Newton Serendipitou…

The relationship between X-ray emission and accretion in X-ray selected AGNs

R. Fanali, A. Caccianiga, P. Severgnini +4

We study the link between the X-ray emission in radio-quiet AGNs and the accretion rate on the central Supermassive Black-Hole (SMBH) using a well-defined and statistically complet…
