Brazil's CH4 emissions over the period 2010–2018 were derived for the three main sectors of activity: anthropogenic, wetland and biomass burning. Our inverse modelling estimates were derived from GOSAT (Greenhouse gases Observing SATellite) satelli

The majority of short gamma-ray bursts (SGRBs) are thought to originate from the merger of compact binary systems collapsing directly to form a black hole. However, it has been proposed that both SGRBs and long gamma-ray bursts (LGRBs) may, on rare o

PHL 1445 : an eclipsing cataclysmic variable with a substellar donor near the period minimum

Autor: Joao Bento, J. W. Rostron, Elmé Breedt, Steven G. Parsons, Madelon C. P. Bours, C. D. J. Savoury, S. P. Littlefair, V. S. Dhillon, T. R. Marsh, R. L. Tunnicliffe, P. Kerry, Isabelle Baraffe, D. I. Sahman, Chris M. Copperwheat, M. J. McAllister, L. K. Hardy, J. Bochinski

We present high-speed, three-colour photometry of the eclipsing dwarf nova PHL 1445, which, with an orbital period of 76.3 min, lies just below the period minimum of ~82 min for cataclysmic variable stars. Averaging four eclipses reveals resolved ecl

A ‘kilonova’ associated with the short-duration γ-ray burst GRB 130603B

Short-duration γ-ray bursts are intense flashes of cosmic γ-rays, lasting less than about two seconds, whose origin is unclear1, 2. The favoured hypothesis is that they are produced by a relativistic jet created by the merger of two compact stellar

We present comprehensive multiwavelength observations of three gamma-ray bursts (GRBs) with durations of several thousand seconds. We demonstrate that these events are extragalactic transients; in particular we resolve the long-standing conundrum of

On the nature of the 'hostless' short GRBs

A significant proportion ($\sim30\%$) of the short-duration gamma-ray bursts (SGRBs) localised by Swift have no detected host galaxy coincident with the burst location to deep limits, and also no high-likelihood association with proximate galaxies on

We present the optical discovery and sub-arcsecond optical and X-ray localization of the afterglow of the short GRB 120804A, as well as optical, near-IR, and radio detections of its host galaxy. X-ray observations with Swift/XRT, Chandra, and XMM-New

GRB 100816A and the nature of intermediate duration gamma-ray bursts

Autor: R. L. Tunnicliffe, Andrew J. Levan

Publikováno v: Proceedings of the International Astronomical Union. 7:415-416

Gamma-ray bursts are normally split into two classes, primarily determined by their observed duration, so called long (> 2s) and short (< 2s) GRBs. There have been many claims of a third duration class, with emission lasting for intermediate periods

Variable X-ray and gamma-ray emission is characteristic of the most extreme physical processes in the Universe, and studying the sources of these energetic photons has been a major driver in astronomy for the past 50 years. Here we present multiwavel
