In this article, a computer algorithm was designed to identify contiguous emission regions, large and elongated enough to serve as GRG candidates, and applied it to the entire 1.4GHz NRAO VLA Sky survey (NVSS) image atlas.Abstract:
We present results of a search for giant radio galaxies (GRGs) larger than 1 Mpc in projected size. We designed a computer algorithm to identify contiguous emission regions, large and elongated enough to serve as GRG candidates, and applied it to the entire 1.4-GHz NRAO VLA Sky survey (NVSS) image atlas. Subsequent visual inspection of 1,000 such regions revealed 15 new GRGs, as well as many other candidate GRGs, some of them previously reported, for which no redshift was known. Our optical spectroscopy of 25 host galaxies with two 2.1-m telescopes in Mexico, and four others with the 10.4-m Gran Telescopio Canarias (GTC), yielded another 24 GRGs. We also obtained higher-resolution radio images with the Karl G. Jansky Very Large Array for some unconfirmed GRG candidates.read more

TL;DR: In this article, the optical variability of the Catalina Real-Time Transient Survey (CRTS) data was used to identify binary supermassive black hole (SMBH) binaries.
Journal ArticleDOI
Indirect and direct search for dark matter
TL;DR: In this article, the authors summarize the status of the field with an emphasis on the complementarity between direct detection in dedicated laboratory experiments, indirect detection in the cosmic radiation, and searches at particle accelerators.
Journal ArticleDOI
Multi-timescale analysis of phase transitions in precessing black-hole binaries
TL;DR: In this article, a multiscale analysis of precessing binary black holes (BBHs) in the post-Newtonian regime has been developed, where the orbital timescale is very short compared to the spin-precession timescale.

Detection of a γ -ray halo around Geminga with the Fermi-LAT data and implications for the positron flux
TL;DR: In this paper, the authors analyzed almost 10 years of the Fermi Large Area Telescope (Fermi-LAT) data and found that an efficiency of about 1% for the conversion of the spin-down energy of the pulsar into a positron excess was required.
Journal ArticleDOI
Suppression of the accretion rate in thin discs around binary black holes
TL;DR: In this paper, the authors investigated the dependence of the accretion rate on the disc thickness around an equal-mass, circular black hole binary system and found that for thick/hot discs, the binary torque does not prevent the gas from penetrating the cavity formed in the disc by the binary.

TL;DR: The NRAO VLA Sky Survey (NVSS) covers the sky north of J2000 at 1.4 GHz as discussed by the authors, including a set of 2326 4?? 4? continuum cubes with three planes containing Stokes I, Q, and U images plus a catalog of almost 2? 106 discrete sources stronger than S 2.5 mJy.

The FIRST Survey: Faint Images of the Radio Sky at twenty centimeters
TL;DR: The first year of the First Radio Sky at Twenty centimeters (FIRST) survey as discussed by the authors was performed using the NRAO Very Large Array (VLA) with a total of 144 hr of time in 1993 April and May was used for a variety of tests, as well as to cover an initial strip of the survey extending between 07{sup h}15{sup m} and 16{suph}30{supm} in a 2{sq_bullet}8 wide declination zone passing through the local zenith.
