Aims. The objective of this work is to adapt a deep neural network model to perform galaxy morphological classification trained from crowd annotations, considering the training sch…
From relics to stripped systems: the environmental origin of compact galaxies
Guangwen Chen, J. Alfonso L. Aguerri, Carlos del Burgo +1
Compact galaxies represent a key population for understanding galaxy evolution, but the relative role of internal structure and environment in shaping their origin remains unclear.…
The Longest-period Young Transiting Exoplanets. A Duo of Puffy Giants inside a Debris Disk
Carlos del Burgo, Alejandro Suárez Mascareño, Ana Heras Pastor +35
We identify two large-radius planets around the F-type star HD 114082 as the longest-period young transiting exoplanets known. From the first transit, detected by NASA's Transiting…
The ALMA survey to Resolve exoKuiper belt Substructures (ARKS) XI: Gas-dust interactions and radial offsets between micron and millimetre-sized grains
J. Olofsson, M. R. Jankovic, S. Marino +22
The dust observed in debris disks is the result of a collisional cascade initiated from km-sized parent bodies. Using near-infrared to sub-millimeter observations, we can pr…
The ALMA survey to Resolve exoKuiper belt Substructures (ARKS) V: Comparison between scattered light and thermal emission
J. Milli, J. Olofsson, M. Bonduelle +33
Debris discs are analogues to our own Kuiper belt around main-sequence stars and are therefore referred to as exoKuiper belts. They have been resolved at high angular resolution at…
The ALMA survey to Resolve exoKuiper belt Substructures (ARKS) VII: Optically thick gas with broad CO gaussian local line profiles in the HD 121617 disc
A. Brennan, L. Matrà, S. Mac Manamon +24
CO gas has been detected in 20 debris discs. We present ALMA observations of the CO-rich HD 121617 debris disc from the ARKS survey. Using high-resolution Band 7 observations…
A radially broad collisional cascade in the debris disk of Ophiuchi observed by JWST
Yinuo Han, Mark Wyatt, Kate Y. L. Su +13
The A1V star Oph, at a distance of 29.7 pc, is known from Spitzer imaging to host a debris disk with a large radial extent and from its spectral energy distribution to host inn…
Single-epoch and Differential Astrometric Microlensing of Quasars
R. Forés-Toribio, E. Mediavilla, J. A. Muñoz +3
We propose and discuss a new experimental approach to measure the centroid shift induced by gravitational microlensing in the images of lensed quasars (astrometric microlensing). O…
Substellar science in the wake of the ESA Euclid space mission
Eduardo L. Martín, Hervé Bouy, Diego Martín +16
The ESA space mission Euclid was launched on July 1st, 2023 and is undergoing its science verification phase. In this invited review we show that Euclid means a before and an after…
Sudden extreme obscuration of a Sun-like main-sequence star: evolution of the circumstellar dust around ASASSN-21qj
Jonathan P. Marshall, Steve Ertel, Francisca Kemper +6
ASASSN-21qj is a distant Sun-like star that recently began an episode of deep dimming events after no prior recorded variability. Here we examine archival and newly obtained optica…
The GAPS program at TNG XLVII: The unusual formation history of V1298 Tau
D. Turrini, F. Marzari, D. Polychroni +33
Observational data from space and ground-based campaigns reveal that the 10-30 Ma old V1298 Tau star hosts a compact and massive system of four planets. Mass estimates for the two…
Identification of Extended Emission Gamma-Ray-Bursts Candidates using Machine Learning
K. Garcia-Cifuentes, R. L. Becerra, F. De Colle +2
Gamma-Ray bursts (GRBs) have been traditionally classified based on their duration. The increasing number of extended emission (EE) GRBs, lasting typically more than 2 seconds but…
Stirred but not shaken: a multi-wavelength view of HD 16743's debris disc
Jonathan P. Marshall, Julien Milli, Elodie Choquet +6
Planetesimals -- asteroids and comets -- are the building blocks of planets in protoplanetary discs and the source of dust, ice and gas in debris discs. Along with planets they com…
The high-albedo, low polarization disk around HD 114082 harbouring a Jupiter-sized transiting planet
N. Engler, J. Milli, R. Gratton +36
We present new optical and near-IR images of debris disk around the F-type star HD 114082. We obtained direct imaging observations and analysed the TESS photometric time series dat…
The SHARDDS survey: limits on planet occurrence rates based on point sources analysis via the Auto-RSM framework
C. -H. Dahlqvist, J. Milli, O. Absil +7
In the past decade, HCI surveys provided new insights about the frequency and properties of substellar companions at separation larger than 5 au. In this context, our study aims to…
HORuS transmission spectroscopy and revised planetary parameters of KELT-7b

Hubble constant and nuclear equation of state from kilonova spectro-photometric light curves
M. A. Pérez-García, L. Izzo, D. Barba +17
The merger of two compact objects of which at least one is a neutron star is signalled by transient electromagnetic emission in a kilonova (KN). This event is accompanied by gravit…
Rapid contraction of giant planets orbiting the 20 million-years old star V1298 Tau
A. Suárez Mascareño, M. Damasso, N. Lodieu +41
Current theories of planetary evolution predict that infant giant planets have large radii and very low densities before they slowly contract to reach their final size after about…
