Since the birth of X-ray Astronomy, spectacular advances have been seen in the imaging, spectroscopic and timing studies of the hot and violent X-ray Universe, and further leaps forward are expected in the future. On the other...
MOONS is the new Multi-Object Optical and Near-infrared Spectrograph currently under construction for the Very Large Telescope (VLT) at ESO. This remarkable instrument combines, for the first time, the collecting power of an 8-m...
Fast Radio Bursts (FRBs) are extra-galactic radio transients which exhibit a
distance-dependent dispersion of their signal, and thus can be used as
cosmological probes. In this article we, for the first time, apply...
The Cherenkov Telescope Array (CTA) is the major next-generation observatory for ground-based very-high-energy gamma-ray astronomy. It will improve the sensitivity of current ground-based instruments by a factor of five to...
We present the second public data release (DR2) from the DECam Local Volume
Exploration survey (DELVE). DELVE DR2 combines new DECam observations with
archival DECam data from the Dark Energy Survey, the DECam Legacy Survey...
We present the results of a search for outer Solar System objects in the full
six years of data (Y6) from the Dark Energy Survey (DES). The DES covered a
contiguous $5000$ deg$^2$ of the southern sky with $\approx 80,000$ $3$...
The Liverpool Telescope is one of the world's premier facilities for time domain astronomy. The time domain landscape is set to radically change in the coming decade, with surveys such as LSST providing huge numbers of transient...
Since the birth of X-ray Astronomy, spectacular advances have been seen in the imaging, spectroscopic and timing studies of the hot and violent X-ray Universe, and further leaps forward are expected in the future. On the other...
Gravitational waves (GWs) cause the apparent position of distant stars to oscillate with a characteristic pattern on the sky. Astrometric measurements (e.g., those made by Gaia) provide a new way to search for GWs. The main...
Exoplanet detection with precise radial velocity (RV) observations is
currently limited by spurious RV signals introduced by stellar activity. We
show that machine learning techniques such as linear regression and...
High-resolution spectroscopy has proven to be a powerful avenue for
atmospheric remote sensing of exoplanets. Recently, ESO commissioned the
CRIRES+ high-resolution infrared spectrograph at VLT. CRIRES+ is a
cross-dispersed...

We describe the validation of the HERA Phase I software pipeline by a series
of modular tests, building up to an end-to-end simulation. The philosophy of
this approach is to validate the software and algorithms used in the Phase...
Large-scale astronomical surveys have the potential to capture data on large
numbers of strongly gravitationally lensed supernovae (LSNe). To facilitate
timely analysis and spectroscopic follow-up before the supernova fades, an...
Exoplanet science is booming. In 20 years our knowledge has expanded
considerably, from the first discovery of a Hot Jupiter, to the detection of a
large population of Neptunes and super-Earths, to the first steps toward...
MOONS is the new Multi-Object Optical and Near-infrared Spectrograph currently under construction for the Very Large Telescope (VLT) at ESO. This remarkable instrument combines, for the first time, the collecting power of an 8-m...
Atmospheric retrievals of exoplanet transmission spectra allow constraints on
the composition and structure of the day-night terminator region. Such
retrievals in the past have typically assumed one-dimensional...
Considerable observational efforts are being dedicated to measuring the
sky-averaged (global) 21-cm signal of neutral hydrogen from Cosmic Dawn and the
Epoch of Reionization. Deriving observational constraints on the...
The Liverpool Telescope is one of the world's premier facilities for time domain astronomy. The time domain landscape is set to radically change in the coming decade, with surveys such as LSST providing huge numbers of transient...
We describe an updated calibration and diagnostic framework, Balrog, used to
directly sample the selection and photometric biases of the Dark Energy
Survey's (DES) Year 3 (Y3) dataset. We systematically inject onto...
