Scripts used to reduce ALMA data in Watson et al. 2014, Nature in press.

Here we supply an archive of the scripts used for the calibration and imaging of the ALMA data for the projects 2011.0.00319.S and 2012.1.00261.S (PI: Johan Ricard). The scripts were used in the reduction of this data for the article by Watson et al., 2014, Nature, in press, entitled "A dusty, normal galaxy in the epoch of reionization". A README file with a description of the individual files is included. Link >>

The Optically Unbiased GRB Host Survey (TOUGH)

TOUGH is a survey of a carefully selected sample of 69 gamma-ray bursts, designed for statistical analysis and future legacy value. The gamma-ray bursts were discovered and localised by the Swift satellite and subsequently followed up from ground. The core survey is based on an ESO Large Programme consisting of deep late R and Ks band imaging (for host identification and photometry) and spectroscopy (for redshift determination and studies of Lyα emission properties). These data have been supplemented by HST and Gemini photometry and X-shooter/VLT spectroscopy. At longer wavelengths, subsamples have been observed by IRAC/Spitzer and with radio observatories. The sample is intended for further investigations with ALMA, EVLA, and JWST. We here make all existing data from the ESO Large Programme and catalogs publicly available. Link >>

Catalog of Mg II absorbers is at the CDS

Here we present a catalog of strong (rest equivalent width Wr>1Å) intervening Mg II absorbers in the SDSS Data Release 7 quasar catalog (2010AJ....139.2360S, Cat. VII/260). The intervening absorbers were found by a semi-automatic algorithm written in IDL - for details of the algorithm see section 2 of our paper.  A subset of the absorbers has been visually inspected - see the MAN_OK flag in the catalog. The number of sightlines searched, tabulated by absorber redshift, i.e. g(z), is available as an ASCII table (for S/N>8 and S/N>15). All  analysis in our paper is based on the SNR>8 coverage, and considers only sight-lines towards non-BAL quasars.

Statistical mechanics approach to collisionless relaxation (DARKexp)

DARKexp describes the distribution of scaled particle energy, ε, in self-gravitating, collisionless systems. It has the simple form, N(ε) ∼ exp(φ0 − ε) − 1 as derived from statistical mechanical principles. For more information, papers on the approach (so far) and the denisity profiles, click the link to the right.

The Gamma-ray burst − supernova connection

Long-duration, soft-spectrum gamma-ray bursts are related to the death of massive stars. The observations of the gamma-ray burst-supernova connection constitute the most direct evidence of this physical link. This website provides basic information on 35 such associations and also links to the recent literature on the subject. Link >>
