Discovery of sulfur oxides in the ejecta of a B[e] supergiant
C. Bordiu, J. Ricardo Rizzo, D. Navarro-Almaida +12
B[e] supergiants represent a rare class of luminous, evolved massive stars surrounded by dusty circumstellar disks. Since their intense UV fields were long thought to sterilize the…
ExoDNN: Boosting exoplanet detection with artificial intelligence. Application to Gaia Data Release 3

We combine Gaia Data Release 3 and artificial intelligence to enhance the current statistics of substellar companions, particularly within regions of the orbital period vs. mass pa…
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
Simon B. De Daniloff, Ángel Bongiovanni, Miguel Sánchez-Portal +21
Galaxy clusters are among the largest and densest structures in the Universe. Their high density generally increases the suppression of star formation, known as quenching, altering…
MeerKAT discovery of 164 compact radio rings toward the Galactic Plane
C. Bordiu, F. Bufano, G. Umana +14
We report the discovery of 164 compact (radius < 1 arcmin) radio rings using MeerKAT 1.3 GHz data from the SARAO MeerKAT Galactic Plane Survey (l=2-60deg, 252-358deg, |b|<1.5deg) a…
Millimetre continuum from LBV stars and their environs. NIKA2 observations and Virtual Observatory data
J. R. Rizzo, C. Bordiu, A. Ritacco
Multi-wavelength studies of their circumstellar environments around LBVs are essential to quantify their feedback at Galactic scales. Dominant emission mechanisms at millimetre wav…
Substellar candidates at the earliest stages: the SUCANES database
A. M. Pérez-García, N. Huélamo, A. García-López +11
Brown dwarfs are the bridge between low-mass stars and giant planets. One way of shedding light on their dominant formation mechanism is to study them at the earliest stages of the…
MeerKAT reveals a ghostly thermal radio ring towards the Galactic Centre
C. Bordiu, M. D. Filipovic, G. Umana +26
We present the serendipitous discovery of a new radio-continuum ring-like object nicknamed Kyklos (J1802-3353), with MeerKAT UHF and L-band observations. The radio ring, which rese…
The CARMENES search for exoplanets around M dwarfs. Telluric absorption corrected high S/N optical and near-infrared template spectra of 382 M dwarf stars
E. Nagel, S. Czesla, A. Kaminski +22
Light from celestial objects interacts with the molecules of the Earth's atmosphere, resulting in the production of telluric absorption lines in ground-based spectral data. Correct…
The rich molecular environment of the luminous blue variable star AFGL 2298
J. R. Rizzo, C. Bordiu, C. Buemi +6
We investigated the molecular environment of AFGL 2298, an obscured Galactic Luminous blue variable (LBV) star which hosts a highly structured circumstellar environment with hints…
Main Sequence to Starburst Transitioning Galaxies: Gamma-ray Burst Hosts at
Jakub Nadolny, Michał Jerzy Michałowski, J. Ricardo Rizzo +8
Star-forming galaxies populate a main sequence (MS), a well-defined relation between stellar mass (M*) and star-formation rate (SFR). Starburst (SB) galaxies lie significantly abov…
The CARMENES search for exoplanets around M dwarfs. Guaranteed time observations Data Release 1 (2016-2020)
I. Ribas, A. Reiners, M. Zechmeister +102
The CARMENES instrument was conceived to deliver high-accuracy radial velocity (RV) measurements with long-term stability to search for temperate rocky planets around a sample of n…
First detection of silicon-bearing molecules in Car
C. Bordiu, J. R. Rizzo, F. Bufano +11
We present ALMA band 6 observations of the luminous blue variable Eta Car, obtained within the ALMAGAL program. We report SiO J=5-4, SiS J=12-11 and SiN N=5-4 emission in the equat…
The interstellar medium in the environment of the supernova-less long-duration GRB 111005A
Aleksandra Leśniewska, M. J. Michałowski, P. Kamphuis +17
Long ( s) gamma ray bursts (GRBs) are associated with explosions of massive stars, although in three instances, supernovae (SNe) have not been detected, despite deep observatio…
Identification and spectroscopic characterization of 128 new Herbig stars
Miguel Vioque, René D. Oudmaijer, Chumpon Wichittanakom +6
We present optical spectroscopy observations of 145 high-mass pre-main sequence candidates from the catalogue of Vioque et al. (2020). From these, we provide evidence for the Herbi…
Raman spectroscopy and planetary exploration: testing the ExoMars/RLS system at the Tabernas Desert (Spain)
Marco Veneranda, Guillermo Lopez-Reyes, Jose Antonio Manrique-Martinez +8
ExoFit trials are field campaigns financed by ESA to test the Rosalind Franklin rover and to enhance collaboration practices between ExoMars working groups. During the first trial,…
SiO, 29SiO, and 30SiO emission from 67 oxygen-rich stars. A survey of 61 maser lines from 7 to 1 mm
J. R. Rizzo, J. Cernicharo, C. Garcia-Miro
Circumstellar environments of oxygen-rich stars are among the strongest SiO maser emitters. Physical processes such as collisions, infrared pumping and overlaps favors the inversio…
