The distribution of equivalent widths in long GRB afterglow spectra

open access: yes, 2012
The extreme brightness of gamma-ray burst (GRB) afterglows and their simple spectral shape make them ideal beacons to study the interstellar medium of their host galaxies through absorption line spectroscopy. Using 69 low-resolution GRB afterglow spectra,

DNA metabarcoding reveals greater plant diversity than morphological seed analysis of bird feces

open access: yesApplications in Plant Sciences, EarlyView.
Abstract Premise Fruit‐eating birds drive seed dispersal in recovering tropical ecosystems, shaping forest regeneration. Molecular techniques, such as DNA metabarcoding, enable diet analysis from feces and can provide complementary frugivory data where dispersal is infrequent, as well as aid in seed identification in hyper‐diverse regions lacking ...

Compact supersymmetric solutions of the heterotic equations of motion in dimensions 7 and 8 [PDF]

open access: yes, 2008
We construct explicit compact solutions with non-zero field strength, non-flat instanton and constant dilaton to the heterotic string equations in dimensions seven and eight.

The Price Gap in Agriculture‐Based Greenhouse Gas Offset Markets

open access: yesAustralian Journal of Agricultural and Resource Economics, EarlyView.
ABSTRACT Today, there is a global effort to reduce greenhouse gas net emissions (GHGNE). For economic well‐being, it is important to identify low‐cost means of net emission offsets. Agriculture and forestry have received considerable attention as a means of supplying emissions offsets, as they contribute nearly 20% of global emissions.

Near-infrared follow-up to the May 2008 activation of SGR 1627-41 [PDF]

open access: yes, 2009
On 28 May 2008, the Swift satellite detected the first reactivation of SGR 1627-41 since its discovery in 1998. Following this event we began an observing campaign in near infrared wavelengths to search for a possible counterpart inside the error ...

AGILE detection of delayed gamma-ray emission from GRB 080514B [PDF]

open access: yes, 2008
GRB 080514B is the first gamma ray burst (GRB), since the time of EGRET, for which individual photons of energy above several tens of MeV have been detected with a pair-conversion tracker telescope.

Migration, Repression and Homosexual Sociability in Francoist Spain: An Analysis of the Case Files of the Special Courts of Barcelona (1965–1975)

open access: yesGender &History, EarlyView.
ABSTRACT In Spain, under General Franco's regime, homosexuality was regarded as an antisocial and dangerous behaviour. It was thus pursued both by the police and judicial courts. The Law on Vagrants and Crooks (1954) and, subsequently, the Law on Dangerousness and Social Rehabilitation (1970) constituted the legal mechanisms used by the dictatorship to

Pre-ALMA observations of GRBs in the mm/submm range

open access: yes, 2011
GRBs generate an afterglow emission that can be detected from radio to X-rays during days, or even weeks after the initial explosion. The peak of this emission crosses the mm/submm range during the first hours to days, making their study in this range ...
