An Optically Targeted Search for Gravitational Waves emitted by Core-Collapse Supernovae during the First and Second Observing Runs of Advanced LIGO and Advanced Virgo
The LIGO Scientific Collaboration, the Virgo Collaboration, B. P. Abbott +1195
We present the results from a search for gravitational-wave transients associated with core-collapse supernovae observed within a source distance of approximately 20 Mpc during the…
GW170104: Observation of a 50-Solar-Mass Binary Black Hole Coalescence at Redshift 0.2
The LIGO Scientific Collaboration, the Virgo Collaboration, B. P. Abbott +1048
We describe the observation of GW170104, a gravitational-wave signal produced by the coalescence of a pair of stellar-mass black holes. The signal was measured on January 4, 2017 a…
A Search for Tensor, Vector, and Scalar Polarizations in the Stochastic Gravitational-Wave Background
The LIGO Scientific Collaboration, the Virgo Collaboration, B. P. Abbott +1097
The detection of gravitational waves with Advanced LIGO and Advanced Virgo has enabled novel tests of general relativity, including direct study of the polarization of gravitationa…
Optically Selected BL Lacertae Candidates from the Sloan Digital Sky Survey Data Release Seven
Richard M. Plotkin, S. F. Anderson, W. N. Brandt +18
We present a sample of 723 optically selected BL Lac candidates from the SDSS DR7 spectroscopic database encompassing 8250 deg^2 of sky; our sample constitutes one of the largest u…
Glimpsing through the high redshift neutral hydrogen fog
S. Gallerani, A. Ferrara, X. Fan +1
We analyze the transmitted flux in a sample of 17 QSOs spectra at 5.74<zem<6.42 to obtain tighter constraints on the volume-averaged neutral hydrogen fraction, xHI, at z~6. We stud…
HYPERION: broad-band X-ray-to-near-infrared emission of Quasars in the first billion years of the Universe
I. Saccheo, A. Bongiorno, E. Piconcelli +41
We aim at characterizing the X-ray-to-optical/near-infrared broad-band emission of luminous QSOs in the first Gyr of cosmic evolution to understand whether they exhibit differences…
