From its first scientific run in 2007, the Virgo detector has constantly been upgraded over the years; since 2017, with the Advanced Virgo project, the detector reached a high sensitivity that allowed the detection of several classes of sources and to investigate new physics. This work reports the Citation: Bersanetti, D.; Patricelli, B.; main hardware upgrades of the detector and the main astrophysical results from the latest five years; Piccinni, O.J.; Piergiovanni, F.; future prospects for the Virgo detector are also presented. -

Gravitational Waves from Neutron Stars: a Review
Publications of the Astronomical Society of Australia (PASA), Vol. 32, e034, 11 pages (2015). C Astronomical Society of Australia 2015; published by Cambridge University Press. doi:10.1017/pasa.2015.35 Gravitational Waves from Neutron Stars: A Review Paul D. Lasky Monash Centre for Astrophysics, School of Physics and Astronomy, Monash University, VIC 3800, Australia Email: [email protected] (Received August 20, 2015; Accepted August 26, 2015) Abstract Neutron stars are excellent emitters of gravitational waves. Squeezing matter beyond nuclear densities invites exotic physical processes, many of which violently transfer large amounts of mass at relativistic velocities, disrupting spacetime and generating copious quantities of gravitational radiation. I review mechanisms for generating gravitational waves with neutron stars. This includes gravitational waves from radio and millisecond pulsars, magnetars, accreting systems, and newly born neutron stars, with mechanisms including magnetic and thermoelastic deformations, various stellar oscillation modes, and core superfluid turbulence. I also focus on what physics can be learnt from a gravitational wave detection, and where additional research is required to fully understand the dominant physical processes at play.

Multimessenger Research before GW170817 Giuseppina Modestino∗ INFN, Laboratori Nazionali di Frascati, I-00044, Frascati (Roma) Italy (Dated: March 4, 2019) Linking the previous research that occurred over the last decades, I will try to provide some objective elements to evaluate the innovation of the joint observation of GW170817 and GRB 170817A and their occurrence detection, in light of preceding experiences regarding the experimental research of association between γ-ray bursts (GRBs) and gravitational waves (GWs). Without debating about the phenomenological properties of astrophysical events, I propose a comparison between that result and the previous experimental research by the interferometer GW community, using a fundamental energy emission law, and including about fifteen years of accredited results regarding coincident detection. From the present review, an intense and old pre-existing activity in the field of multimessenger observations emerges giving a first interesting fact. The widespread opinion that joint detection of GW170817 and GRB 170817A has opened a new method in astrophysics does not find a robust reason. Moreover, some critical points highlight. In the past, applying the same multimessenger method, numerous measures have been taken towards much brighter and much closer sources. Then, it would have been plausible to see joint signals even taking into account a worse sensitivity of the instruments of the time. At current time, there is only one event associated to a subthreshold GRB, compared to a long list of candidate events that would have been much more revealing. If these inconsistencies are admissible enough to lead to a claim, then the question arises about the interpretation of the long previous measurements carried out applying the same multimessenger observation method but without positive responses. -

Theory and Experiment in Gravitational Physics Clifford M
Cambridge University Press 978-1-107-11744-0 — Theory and Experiment in Gravitational Physics Clifford M. Will Frontmatter More Information Theory and Experiment in Gravitational Physics The 2015 centenary of the publication of Einstein’s general theory of relativity and the first detection of gravitational waves have focused renewed attention on the question of whether Einstein was right. This review of experimental gravity provides a detailed survey of the intensive testing of Einstein’s theory of gravity, including tests in the emerging strong-field dynamical regime. It discusses the theoretical frameworks needed to analyze gravitational theories and interpret experiments. Completely revised and updated, this new edition features coverage of new alternative theories of gravity, a unified treatment of gravitational radiation, and the implications of the latest binary pulsar observations. It spans the earliest tests involving the solar system to the latest tests using gravitational waves detected from merging black holes and neutron stars. It is a comprehensive reference for researchers and graduate students working in general relativity, cosmology, particle physics, and astrophysics. Cliford M. Will is Distinguished Professor of Physics at the University of Florida and Chercheur Associe´ at the Institut d’Astrophysique de Paris.
