We investigate the redshift evolution of disc- and bulge-dominated galaxies using a mass-complete sample of $\sim$14 000 galaxies from the CANDELS survey, selected with $H_{\rm mag} \le 24$, $M_{\rm stellar} \ge 10^9,{\rm M}_\odot$, and spanning $0.2 \le z \le 2.4$. Adopting an unbiased morphological classification, free from visual inspection or

We present the analysis of a microlensing event KMT-2022-BLG-0086 of which the overall light curve is not described by a binary-lens single-source (2L1S) model, which suggests the existence of an extra lens or an extra source. We found that the event is best explained by the binary-lens binary-source (2L2S) model, but the 2L2S model is only favored

GRB 221009A is the brightest gamma-ray burst (GRB) observed to date. Extensive observations of its afterglow emission across the electromagnetic spectrum were performed, providing the first strong evidence of a jet with a nontrivial angular structure in a long GRB. We carried out an extensive observation campaign in very-high-energy (VHE) gamma

We present the discovery of 11 new transiting brown dwarfs (BDs) and low-mass M dwarfs from NASA's Transiting Exoplanet Survey Satellite (TESS) mission: TOI-2844, TOI-3122, TOI-3577, TOI-3755, TOI-4462, TOI-4635, TOI-4737, TOI-4759, TOI-5240, TOI-5467, and TOI-5882. They consist of five BD companions and six very-low-mass stellar companions ranging

This paper presents the first effort to Extend the Investigation of Stellar Populations In RElics (E-INSPIRE). We present a catalogue of 430 spectroscopically confirmed ultra-compact massive galaxies (UCMGs) from the Sloan Digital Sky Survey at redshifts $0.01< z< 0.3$. This increases the original INSPIRE sample eightfold, bridging the gap with the

Central to our understanding of stellar evolution and its impact on processes in our Galaxy and across the Universe is the study of mass-loss. While the general framework is well established, recent JWST observations of objects like NGC 3132 have revealed intricate nebular structures, suggesting complex mass-loss processes likely driven by multiple
