A possible sub-kiloparsec dual AGN buried behind the galaxy curtain
P. Severgnini, V. Braito, C. Cicone +11
Although thousands of galaxy mergers are known, only a handful of sub-kiloparsec-scale supermassive black hole (SMBH) pairs have been confirmed so far, leaving a huge gap between t…
ALMA [CI] observations of NGC6240: a puzzling molecular outflow, and the role of outflows in the global factor of (U)LIRGs
Claudia Cicone, Paola Severgnini, Padelis P. Papadopoulos +9
We present ALMA and ACA [CI] ([CI](1-0)) observations of NGC6240, which we combine with ALMA CO(2-1) and IRAM PdBI CO(1-0) data to study the physical propertie…
A deep Chandra observation of the interacting star-forming galaxy Arp 299
K. Anastasopoulou, A. Zezas, L. Ballo +1
We present results from a 90 ks Chandra ACIS-S observation of the X-ray luminous interacting galaxy system Arp 299 (NGC 3690/IC 694). We detect 25 discrete X-ray sources with lumin…
WISE colours and star-formation in the host galaxies of radio-loud narrow-line Seyfert 1
A. Caccianiga, S. Anton, L. Ballo +7
We investigate the mid-infrared properties of the largest (42 objects) sample of radio-loud narrow-line Seyfert 1 (RL NLS1) collected to date, using data from the Wide-field Infrar…
The merger fraction of active and inactive galaxies in the local Universe through an improved non-parametric classification
Stefano Cotini, Emanuele Ripamonti, Alessandro Caccianiga +5
We investigate the possible link between mergers and the enhanced activity of supermassive black holes (SMBHs) at the centre of galaxies, by comparing the merger fraction of a loca…
Heavily obscured AGN with SIMBOL-X
R. Della Ceca, A. Caccianiga, P. Severgnini
By comparing an optically selected sample of narrow lines AGN with an X-ray selected sample of AGN we have recently derived an estimate of the intrinsic (i.e. before absorption) 2-…
