The polishing of WEAVE spectrograph collimator mirror
WEAVE is the new wide field multi-object and integral field survey facility for the prime focus of the 4.2 m William Herschel Telescope. It is located at the...
The population of barred galaxies in the MACS J0647.8+7015 galaxy cluster at z=0.59
We study the bar fraction in the MACS J0647.8+7015 cluster of galaxies at z=0.59 using the observations obtained with the NIRCam instrument mounted on the JWST...
The population of Planetary Nebulae in the Milky Way
Extensive surveys of the Milky Way have provided a global view of the population of planetary nebulae in the Milky Way. Their chemical, dynamical, and...
The Possible Origins of the VR Magnification Ratios of Q0957+561AB
We present VR magnification ratios of the double quasar Q0957+561AB, which are inferred from frames taken with the 2.56m Nordic Optical Telescope. From two...
The post-common-envelope binary central star of the planetary nebula ETHOS 1
The central star of ETHOS 1 is known to be a post-common-envelope binary. Simultaneous modelling of newly-acquired light and radial velocity curves reveal the...
We present our on-going project to unveil the post-nova population by re-discovering old novae that have been lost after the initial outburst and in which the...
The Potential of Integral Field Spectroscopy Observing Extrasolar Planet Transits
We explore the use of Integral Field Spectroscopy (IFS) for observing extrasolar planet transits. We show that IFS can improve the photometric accuracy in high...
The Pre-flight Calibration of the ISOPHOT Instrument
Extensive characterisation of subsystems such as detectors and their curing, preamplifiers, filters, on-board secondary standard sources and cryomechanisms were...
