BLACK HOLE MERGERS. “This first gravitational wave event, GW150914, appears to have been caused by the merger to two fairly massive (∼30 M⊙) black holes. Subsequent detections of a BBH mergers (GW151226 and GW170104) and a candidate BBH event (LVT151012) have allowed more robust estimates of the local BBH merger rate density and have confirmed the existence of black holes involved in these mergers with masses that range from 7.5 to 36  M⊙.” (BBH = binary black hole). https://lnkd.in/d8Jh7TB View in LinkedIn

A FIRST. “With the first detection of gravitational waves, the Laser Interferometer Gravitational-Wave Observatory (LIGO) simultaneously confirmed a fundamental prediction of General Relativity and discovered the first known binary black hole (BBH) merger.” https://lnkd.in/d8Jh7TB View in LinkedIn

THE LEAP. “In this Letter, an analogue of Einstein’s general relativity, with appropriate restrictions to highlight spatial, rather than temporal, behaviour, is proposed as a preliminary attempt towards an infrared continuum description.” (From sand clumping to quantum phenomena). https://lnkd.in/dusKMKM View in LinkedIn

MODEL. “The great variety of observed and simulated phenomena pertaining to granular matter motivates attempts to construct a simple unified description in the infrared, which captures the essence of the properties without depending too strongly on the underlying microscopics.” https://lnkd.in/dusKMKM View in LinkedIn

CRITICAL POINTS. “Despite this, ‘critical behaviour’ similar to thermal critical phenomena, characterized by a correlation length that diverges at the jamming-unjamming transition, and power-law critical exponents, have been observed in such materials.” https://lnkd.in/dusKMKM View in LinkedIn
