Characterization of a sample of -ray active galactic nuclei
Alberto Ulgiati, Paolo Padovani, Paolo Giommi +2
We analyse 77 \textit{Fermi} sources and their potential low-energy counterparts previously proposed in the literature. These sources were classified as active galactic nuclei, mai…
Identifying multiplets of IceCube alert events
Martina Karl, Paolo Padovani, Paolo Giommi
The IceCube Neutrino Observatory publishes "alert events", i.e. detections of high-energy neutrinos with a moderate-to-high probability of being of astrophysical origin. While some…
The Revised Third Cambridge Catalogue at 60: To Jet or Not to Jet ...
Peter Barthel, Paolo Padovani
Sixty years after the publication of the seminal 3CR catalogue, astronomers are getting to grips with the nature of the radio emissions in active galaxies: black-hole-accretion- an…
The Extremely Large Telescope
Paolo Padovani, Michele Cirasuolo
Extremely large telescopes (ELTs) are considered worldwide to be one of the highest priorities in ground-based astronomy. The European Southern Observatory (ESO) is developing an E…
A simplified view of blazars: the very high energy gamma-ray vision
P. Padovani, P. Giommi
We have recently proposed a simplified scenario for blazars in which these sources are classified as flat-spectrum radio quasars or BL Lacs according to the prescriptions of unifie…
The AGN content of deep radio surveys and radio emission in radio-quiet AGN. Why every astronomer should care about deep radio fields
P. Padovani, M. Bonzini, N. Miller +5
We present our very recent results on the sub-mJy radio source populations at 1.4 GHz based on the Extended Chandra Deep Field South VLA survey, which reaches ~ 30 μJy, with detail…
A simplified view of blazars: the gamma-ray case
P. Giommi, P. Padovani, G. Polenta
We have recently proposed a new simplified scenario where blazars are classified as flat-spectrum radio quasars (FSRQs) or BL Lacs according to the prescriptions of unified schemes…
A simplified view of blazars: why BL Lacertae is actually a quasar in disguise
P. Padovani, P. Giommi, G. Polenta +3
We put forward a scenario where blazars are classified as flat-spectrum radio quasars, BL Lacs, low synchrotron, or high synchrotron peaked objects according to a varying combinati…
The Radio - X-ray relation as a star formation indicator: Results from the VLA--E-CDFS Survey
S. Vattakunnel, P. Tozzi, F. Matteucci +10
In order to trace the instantaneous star formation rate at high redshift, and hence help understanding the relation between the different emission mechanisms related to star format…
The VLA Survey of the Chandra Deep Field South. V. Evolution and Luminosity Functions of sub-mJy radio sources and the issue of radio emission in radio-quiet AGN
P. Padovani, N. Miller, K. I. Kellermann +3
We present the evolutionary properties and luminosity functions of the radio sources belonging to the Chandra Deep Field South VLA survey, which reaches a flux density limit at 1.4…
The VLA Survey of the Chandra Deep Field South. IV. Source Population
P. Padovani, V. Mainieri, P. Tozzi +5
We present a detailed analysis of 256 radio sources from our deep (flux density limit of 42 microJy at the field centre at 1.4 GHz) Chandra Deep Field South 1.4 and 5 GHz VLA surve…
ROXA J081009.9+384757.0: a erg/s blazar with hard X-ray synchrotron peak or a new type of radio loud AGN?
P. Giommi, E. Massaro, P. Padovani +10
We report the discovery of ROXA J081009.9+384757.0 = SDSS J081009.9+384757.0, a z=3.95 blazar with a highly unusual Spectral Energy Distribution (SED). This object was first notice…
BL Lac X-ray Spectra: simpler than we thought
Eric S. Perlman, Timothy Daugherty, Anuradha Koratkar +10
We report results from {\it XMM-Newton} observations of thirteen X-ray bright BL Lacertae objects, selected from the {\it Einstein} Slew Survey sample. The spectra are generally we…
The Lyman-alpha forest of a Lyman Break Galaxy: VLT Spectra of MS1512-cB58 at z=2.724
S. Savaglio, N. Panagia, P. Padovani
The high redshift galaxy MS1512-cB58 (z=2.724, m_V=20.64) has been observed with the very efficient high resolution echelle spectrograph VLT/UVES. Although this is a very challengi…
BeppoSAX Observations of 1 Jy BL Lacertae Objects. I
P. Padovani, L. Costamante, P. Giommi +6
We present new BeppoSAX observations of seven BL Lacertae objects selected from the 1 Jy sample plus one additional source. The collected data cover the energy range 0.1 - 10 keV (…
