The ubiquitous presence of Galactic cirri in deep optical images represents a major obstacle to study the low surface brightness features of extragalactic...
Galactic extinction laws - II. Hidden in plain sight, a new interstellar absorption band at 7700 Å broader than any known DIB
We have detected a broad interstellar absorption band centred close to 7700 Å and with a full width at half-maximum (FWHM) of 176.6 ± 3.9 Å. This is the first...
Galaxy Evolution Studies with the SPace IR Telescope for Cosmology and Astrophysics (SPICA): The Power of IR Spectroscopy
IR spectroscopy in the range 12-230 μm with the SPace IR telescope for Cosmology and Astrophysics (SPICA) will reveal the physical processes governing the...
Galaxy merger challenge: A comparison study between machine learning-based detection methods
Aims: Various galaxy merger detection methods have been applied to diverse datasets. However, it is difficult to understand how they compare. Our aim is to...
GJ 3090 b: one of the most favourable mini-Neptune for atmospheric characterisation
We report the detection of GJ 3090 b (TOI-177.01), a mini-Neptune on a 2.9-day orbit transiting a bright (K = 7.3 mag) M2 dwarf located at 22 pc. The planet was...
GLACE survey: OSIRIS/GTC multi-object spectroscopy of the rich galaxy cluster ZwCl 0024.0+1652 at z∼0.4: III. The mass–SFR relation and the quenching of cluster galaxies
Context. Galaxy clusters are among the largest and densest structures in the Universe. Their high density generally increases the suppression of star formation...
Glancing through the debris disk: Photometric analysis of DE Boo with CHEOPS
Aims: DE Boo is a unique system, with an edge-on view through the debris disk around the star. The disk, which is analogous to the Kuiper belt in the Solar...
Glancing Views of the Earth: From a Lunar Eclipse to an Exoplanetary Transit
It has been posited that lunar eclipse observations may help predict the in-transit signature of Earth-like extrasolar planets. However, a comparative analysis...
