Submillimetre imaging of NGC 3079
(2000-02-01)Submillimetre mapping observations of the active edge-on spiral galaxy NGC 3079 are presented. These maps at 850 and 450 μm were made with the Submillimetre Common User Bolometer Array (SCUBA) at the James Clerk Maxwell ... -
A submillimetre imaging polarimeter at the James Clerk Maxwell Telescope
(2003-04)A polarimeter has been built for use with the Submillimetre Common-User Bolometer Array (SCUBA), on the James Clerk Maxwell Telescope (JCMT) in Hawaii. SCUBA is the first of a new generation of highly sensitive submillimetre ... -
Submillimetre Observations of Clusters of Galaxies
(2020-03-01)Advances in submillimetre astronomy has opened the doors to carrying out surveys and high-resolution imaging of intense star forming galaxies out to and beyond the cosmic star-formation peak (ɀ ≈ 1- 4). The Submillimetre ... -
Submillimetre photometry of post-asymptotic giant branch stars
(2002)Stars in the post-asymptotic giant branch (post-AGB) phase of evolution are surrounded by detached circumstellar envelopes containing dust which emits thermally in the mid- and far-infrared. Here we present 850-μm SCUBA ... -
Submillimetre Polarimetry of Blazars
(Astronomical Society of the Pacific, 1996)We report on preliminary results from the first monitoring campaign of the submillimetre polarization of a sample of Blazars. The observations have been carried out with the James Clerk Maxwell Telescope between 1991 and 1994. -
Submillimetre polarization and constraints on dust grain alignment
(1999)Polarization at 800 and 1100um has been observed in the star-forming regions Mon R2, DR21 and W3-IRS4. These data have been used to test proposed mechanisms for producing polarized dust emission in the submillimetre. It ... -
A Submillimetre Study of Massive Star Formation Within the W51 Complex and Infrared Dark Clouds
(2012-01-13)Despite its importance the fundamental question of how massive stars form remains unanswered, with improvements to both models and observations having crucial roles to play. To quote Bate et al. (2003) computational models ... -
A submillimetre-bright z~3 overdensity behind a z~1 supercluster revealed by SCUBA-2 and Herschel
(2013-11)We present a wide-field (30 arcmin diameter) 850 μm Submillimetre Common-User Bolometer Array-2 map of the spectacular three-component merging supercluster, RCS 231953+00, at z = 0.9. The brightest submillimetre galaxy ... -
Submm-bright X-ray absorbed QSOs at z~2 : insights into the co-evolution of AGN and star-formation
(2015-03-21)We have assembled a sample of 5 X-ray-absorbed and submm-luminous type 1 QSOs at $z \sim 2$ which are simultaneously growing their central black holes through accretion and forming stars copiously. We present here the ... -
Substance Related Exogenous Psychosis: a post-modern syndrome
(2020-06-25)The past two decades have been marked by dramatic social changes, widely characterized by the term “postmodern”. These major transformations have had profound and complex implications for psychiatry, influencing mental ... -
Substance use and misuse - Legal highs
(Centre for Pharmacy Post Graduate Education (CPPE), 2016-09-21)This is an update to the online course on substance misuse designed for post-graduate pharmacists. The update was reviewed by Public Health England and the CPPE. It was published by the CPPE in Sep 2016. It is accessed by ... -
Substance Use Disorders and Violence
(Springer International Publishing AG, part of Springer Nature, 2020-01-01)Substance use seems to be associated with increased prevalence levels of violent behaviour in both general population and psychiatric patients, with ‘dual-diagnosis’ clients showing high rates of risky and criminal behaviour ... -

Substance use in the club scene of Rome : a pilot study
(2014-08-28)Over the last few years, a wide number of unregulated substances have been marketed on the Web and in smart and head shops; they are usually advertised as legal alternatives to commonly known drugs and are defined as “smart ... -
The substellar companion in the eclipsing white dwarf binary SDSS J141126.20+200911.1
(2014-12-01)We present high time resolution SDSS-g′ and SDSS-z′ light curves of the primary eclipse in SDSS J141126.20+200911.1, together with time-resolved X-Shooter spectroscopy and near-infrared (NIR) JHKs photometry. Our observations ... -
Substellar companions and the formation of hot subdwarf stars
(American Institute of Physics (AIP), 2011)We give a brief review over the observational evidence for close substellar companions to hot subdwarf stars. The formation of these core helium-burning objects requires huge mass loss of their red giant progenitors. It ... -
Substitutional potential of mephedrone : An analysis of the subjective effects
(2013-07)In the past 25–30 years, a large number of synthetic and non-synthetic drugs have appeared on the recreational scene, but with the exception of 4-methylmethcathinone (mephedrone), none of these substances reached the ...
