Unsupervised Machine Learning for the Classification of Astrophysical X-ray Sources
Víctor Samuel Pérez-Díaz, Juan Rafael Martínez-Galarza, Alexander Caicedo +1
The automatic classification of X-ray detections is a necessary step in extracting astrophysical information from compiled catalogs of astrophysical sources. Classification is usef…
Probing supermassive black hole growth and its dependence on stellar mass and star-formation rate in low-redshift galaxies
O. Torbaniuk, M. Paolillo, R. D'Abrusco +4
We present an improved study of the relation between supermassive black hole growth and their host galaxy properties in the local Universe (z < 0.33). To this end, we build an exte…
Optical spectroscopic observations of gamma-ray blazar candidates. X. Results from the 2018--2019 SOAR and OAN-SPM observations of blazar candidates of uncertain type
Raniere de Menezes, Raul A. Amaya-Almazán, Ezequiel J. Marchesini +14
The fourth Fermi Large Area Telescope Source Catalog (4FGL) lists over 5000 gamma-ray sources with statistical significance above 4. About 23% of the sources listed in this cata…
Optical Spectroscopic Observations of Gamma-ray Blazar Candidates. V. TNG, KPNO, and OAN Observations of Blazar Candidates of Uncertain Type in the Northern Hemisphere
N. Álvarez Crespo, N. Masetti, F. Ricci +12
The extragalactic -ray sky is dominated by emission from blazars, a peculiar class of active galactic nuclei (AGNs). Many of the -ray sources included in Fermi -Large Area Te…
The Third Catalog of Active Galactic Nuclei Detected by the Fermi Large Area Telescope
M. Ackermann, M. Ajello, W. Atwood +139
The third catalog of active galactic nuclei (AGNs) detected by the Fermi-LAT (3LAC) is presented. It is based on the third Fermi-LAT catalog (3FGL) of sources detected between 100…
Unveiling the nature of the unidentified gamma-ray sources III: gamma-ray blazar-like counterparts at low radio frequencies
F. Massaro, R. D'Abrusco, M. Giroletti +5
About one third of the gamma-ray sources listed in the second Fermi LAT catalog (2FGL) have no firmly established counterpart at lower energies so being classified as unidentified…
Searching for new gamma-ray blazar candidates in the 3rd Palermo BAT Hard X-ray Catalog with WISE
A. Maselli, F. Massaro, G. Cusumano +6
We searched for gamma-ray blazar candidates among the 382 unidentified hard X-ray sources of the 3rd Palermo BAT Catalog (3PBC) obtained from the analysis of 66 months of SWIFT-BAT…
The radial distribution of X-ray Binaries and Globular Clusters in NGC 4649 and their relation with the local stellar mass density
S. Mineo, G. Fabbiano, R. D'Abrusco +7
We investigate the radial distribution of the low-mass X-ray binary (LMXB) population in the elliptical galaxy NGC 4649, using Chandra and Hubble data to separate the field and glo…
