Extended Theories of Gravity can be considered as a new paradigm to cure shortcomings of
General Relativity at infrared and ultraviolet scales. They are an approach that, by …

Multi-messenger astrophysics, a long-anticipated extension to traditional multiwavelength
astronomy, has emerged over the past decade as a distinct discipline providing unique and …

Beyond Einstein's Gravity is a graduate level introduction to extended theories of gravity and
cosmology, including variational principles, the weak-field limit, gravitational waves …

KAGRA is a newly build gravitational wave observatory, a laser interferometer with 3 km arm
length, located in Kamioka, Gifu, Japan. In this paper, one of a series of articles featuring …

Significant progress has been made in recent years on the development of gravitational-
wave detectors. Sources such as coalescing compact binary systems, neutron stars in low …

Gravitational wave science should transform in this decade from a study of what has not
been seen to a full-fledged field of astronomy in which detected signals reveal the nature of …

Autonomous gravitational-wave searches—fully automated analyses of data that run without
human intervention or assistance—are desirable for a number of reasons. They are …

We carry out two searches for periodic gravitational waves using the most sensitive few
hours of data from the second LIGO science run. Both searches exploit fully coherent …

We report here the non-detection of gravitational waves from the merger of binary–neutron
star systems and neutron star–black hole systems during the first observing run of the …

We analyzed the available LIGO data coincident with GRB 070201, a short-duration, hard-
spectrum γ-ray burst (GRB) whose electromagnetically determined sky position is coincident …
