Following the 2022 alert of a TESS object of interest transiting TOI-5624 (a G7, Vstar ~100pc away), a CHEOPS campaign in 2023 detected four planetary signals at P_b_~3.4,...

A particularly intriguing subclass of rocky exoplanets are the ultra- short period (USP) worlds that orbit their host stars in less than a day. These planets are particularly...

JWST observations of the Orion Bar have revealed rich and diverse Polycyclic Aromatic Hydrocarbon (PAH) emission. These observations allow for the first time a comprehensive...

The Neptunian desert is a distinct lack of Neptune-sized planets at short orbital periods, purportedly carved by photoevaporation and tidal circularization following...

A statistically significant sampling of H_2_ rotational excitation in the diffuse interstellar medium (ISM) is essential to identify its dominant excitation mechanisms and...

The Hubble Missing Globular Cluster Survey (MGCS) has taken one of the last opportunities to complete the census of Galactic globular clusters (GCs) started by past Hubble Space...

Galaxy major mergers are a potential mechanism for triggering active galactic nuclei (AGN) activity, but their role remains debated, particularly beyond the local Universe. We...

We present an updated atlas of spectra from the Low-Resolution Spectrometer (LRS) on the Infrared Astronomical Satellite (IRAS), which took spectra from 7.67 to 22.73{mu}m with...

Active Galactic Nuclei (AGN) outflows can regulate host galaxy evolution via AGN feedback. Ionised gas outflows have been linked to enhanced radio emission. In the first paper...

We present the design and observations of low-resolution JWST/NIRSpec PRISM spectroscopy from the Ultradeep NIRSpec and NIRCam ObserVations before the Epoch of Reionization...

We report JWST NIRSpec/G395H observations of TOI-1685 b, a hot rocky super-Earth orbiting an M2.5V star, during a full orbit. We obtain transmission and emission spectra of the...

The properties of the Milky Way's nuclear stellar disc give crucial information on the epoch of bar formation. Mira variables are promising bright candidates to study the...

Active galactic nuclei (AGNs) play a vital role in the evolution of galaxies over cosmic time, significantly influencing their star formation and growth. As obscured AGNs are...

We catalogue the 443 bright supernovae (SNe) discovered by the All-Sky Automated Survey for Supernovae (ASAS-SN) in 2018-2020 along with the 519 SNe recovered by ASAS-SN and 516...

We fit archival near-IR spectra of ~300 brown dwarfs with atmosphere models from the Sonora and Phoenix groups. Using the parameters of the best- fit models as estimates for the...

We present the clump populations detected in 18 lensed galaxies at redshifts 1-- 8.5 within the lensing cluster field SMACS0723. The recent JWST Early Release Observations of...

Using the Lyman Dropout technique, we identify 148 candidate radio sources at z ~> 4-7 from the 887.5 MHz Australian Square Kilometre Array Pathfinder (ASKAP) observations of...

The discovery of infant (<50Myr), close-in (<30-day-period) planets is vital in understanding the formation mechanisms that lead to the distribution of mature transiting...

The detection and characterization of habitable planets around nearby stars persist as some of the foremost objectives in contemporary astrophysics. This work investigates the...

The James Webb Space Telescope (JWST) enables the identification of quiescent galaxies (QGs) out to early epochs, offering a transformative view of their evolution. However,...
