X-ray background measurements with XMM-Newton EPIC
We discuss the methods used to compile a high signal-to-noise dataset representative of both the instrumental and cosmic background signal measured at high galactic latitude by the XMM-Newton EPIC
The association of GRB 060218 with a supernova and the evolution of the shock wave
A supernova is caught in the act of exploding, directly observing the shock break-out, which indicates that the GRB progenitor was a Wolf–Rayet star.
The nature and origin of Seyfert warm absorbers
We collate the results of recent high resolution X-ray spectroscopic observations of 23 AGN, and use the resulting information to try to provide answers to some of the main open questions about warm
Deep radio imaging of the SCUBA 8-mJy survey fields: submillimetre source identifications and redshift distribution
The SCUBA 8-mJy survey is the largest submillimetre (submm) extragalactic mapping survey undertaken to date, covering 260arcmin 2 to a 4� detection limit of ≃8mJy at 850µm, centred on the Lockman
A short γ-ray burst apparently associated with an elliptical galaxy at redshift z = 0.225
Gamma-ray bursts (GRBs) come in two classes: long (> 2 s), soft-spectrum bursts and short, hard events. Most progress has been made on understanding the long GRBs, which are typically observed at
The Herschel Multi-tiered Extragalactic Survey: HerMES
The Herschel Multi-tiered Extragalactic Survey (HerMES) is a legacy programme designed to map a set of nested fields designed to facilitate redshift determination, rapidly identify unusual objects and understand the relationships between thermal emission from dust and other processes.
The Star Formation History of the Universe as Revealed by Deep Radio Observations
Discerning the exact nature of the sub-mJy radio population has been historically difficult due to the low luminosity of these sources at most wavelengths. Using deep ground based optical follow-up
Combined long and short time-scale X-ray variability of NGC 4051 with RXTE and XMM-Newton
We present a comprehensive examination of the X-ray variability of the narrow-line Seyfert 1 (NLS 1) galaxy NGC 405 1, one of the most variable active galactic nuclei (AGN) in the sky. We combine
Herschel and SCUBA-2 imaging and spectroscopy of a bright, lensed submillimetre galaxy at z = 2.3
We present a detailed analysis of the far-infrared (-IR) properties of the bright, lensed, z = 2.3, submillimetre-selected galaxy (SMG), SMM J2135-0102 (hereafter SMM J2135), using new observations
The evolution of the near-infrared galaxy luminosity function and colour bimodality up to z = 2 from the UKIDSS Ultra Deep Survey Early Data Release
We present new results on the cosmological evolution of the near-infrared (near-IR) galaxy luminosity function (LF), derived from the analysis of a new sample of ∼22 000 KAB≤ 22.5 galaxies selected
