The two-colour EMCCD instrument for the Danish 1.54 m telescope and SONG
We report on the implemented design of a two-colour instrument based on electron-multiplying CCD (EMCCD) detectors. This instrument is currently installed at...
The Type II-plateau Supernova 2017eaw in NGC 6946 and Its Red Supergiant Progenitor
We present extensive optical photometric and spectroscopic observations, from 4 to 482 days after explosion, of the Type II-plateau (II-P) supernova (SN)...
The Typical Massive Quiescent Galaxy at z ∼ 3 is a Post-starburst
We have obtained spectroscopic confirmation with Hubble Space Telescope WFC3/G141 of a first sizeable sample of nine quiescent galaxies at 2.4 < z < 3.3. Their...
The UK Infrared Telescope M 33 monitoring project - V. The star formation history across the galactic disc
We have conducted a near-infrared monitoring campaign at the UK Infrared Telescope of the Local Group spiral galaxy M 33 (Triangulum). On the basis of their...
We describe the goals, design, implementation, and initial progress of the UKIRT Infrared Deep Sky Survey (UKIDSS), a seven-year sky survey which began in 2005...
The UKIRT Infrared Deep Sky Survey Early Data Release
This paper defines the UKIRT Infrared Deep Sky Survey (UKIDSS) Early Data Release (EDR). UKIDSS is a set of five large near-infrared surveys being undertaken...
The ultracool helium-atmosphere white dwarf companion of PSR J0740+6620?
We report detection of the likely companion of the binary millisecond pulsar (MSP) J0740+6620 with the Gran Telescopio Canarias in the r' and i' bands. The...
The ultraluminous X-ray source NGC 1313 X-2. Its optical counterpart and environment
NGC 1313 X-2 is one of the brightest ultraluminous X-ray sources in the sky, at both X-ray and optical wavelengths; therefore, quite a few studies of available...
