Facility class Rayleigh beacon AO system for the 4.2m William Herschel Telescope
R. G. M. Rutten, P. Clark, R. M. Myers +9
A rationale is presented for the use of a relatively low-altitude Rayleigh Laser Guide Star to provide partial adaptive optics correction across a large fraction of the sky on the…
The nuclear transient AT 2017gge: a tidal disruption event in a dusty and gas-rich environment and the awakening of a dormant SMBH
F. Onori, G. Cannizzaro, P. G. Jonker +28
We present the results from a dense multi-wavelength (optical/UV, near-infrared (IR), and X-ray) follow-up campaign of the nuclear transient AT2017gge, covering a total of 1698 day…
TOPoS: I. Survey design and analysis of the first sample
E. Caffau, P. Bonifacio, L. Sbordone +14
The metal-weak tail of the metallicity distribution function (MDF) of the Galactic Halo stars contains crucial information on the formation mode of the first generation of stars. T…
A nearby superluminous supernova with a long pre-maximum 'plateau' and strong CII features
J. P. Anderson, P. J. Pessi, L. Dessart +63
Super-luminous supernovae (SLSNe) are rare events defined as being significantly more luminous than normal terminal stellar explosions. The source of the extra powering needed to a…
ScotGrid: A Prototype Tier 2 Centre
A. Earl, P. Clark, S. Thorn
ScotGrid is a prototype regional computing centre formed as a collaboration between the universities of Durham, Edinburgh and Glasgow as part of the UK's national particle physics…
Multiwavelength observations of the extraordinary accretion event AT2021lwx
P. Wiseman, Y. Wang, S. Hönig +43
We present observations from X-ray to mid-infrared wavelengths of the most energetic non-quasar transient ever observed, AT2021lwx. Our data show a single optical brightening by a…
