GPUPHOT: A Python Framework for High-Performance GPU-Accelerated Photometry and Distributed Astronomical Data Reduction
Samuel Lemes-Perera, Miguel R. Alarcon, Miquel Serra-Ricart +1
We present GPUPHOT, an open-source Python framework for GPU-accelerated real-time photometry and astrometry of astronomical CCD and scientific CMOS images. Four of its seven stages…
Long-baseline ATLAS photometry of the seven main-belt asteroid targets of the Emirates Mission to the Asteroid Belt
Nicolas Erasmus, Josef Ďurech, David E. Trilling +6
The Emirates Mission to the Asteroid Belt (EMA) will use the MBR Explorer spacecraft to fly past six main-belt asteroids -- (10253) Westerwald, (623) Chimaera, (13294) Rockox, (880…
Serendipitous discovery of an almost-dark galaxy in the Virgo Cluster
Minh Ngoc Le, Ignacio Trujillo, Sergio Guerra Arencibia +9
Analogues of extreme Local Group galaxies with very low surface brightnesses and large effective radii must exist elsewhere, still hidden due to current detection limits. We report…
Size, shape, density, and atmospheric limit of (50000) Quaoar revealed from 14 years of stellar occultation
Giuliano Margoti, Felipe Braga-Ribas, José Luis Ortiz +173
We present results from 28 stellar occultations by the large Trans-Neptunian Object (50000) Quaoar registered between 2018 and 2025. By performing a joint analysis of this occultat…
Dust colour, phase behaviour, and Monte Carlo modelling of interstellar comet 3I/ATLAS from 4 au pre- to 4 au post-perihelion
F. Moreno, M. Serra-Ricart, J. Licandro +4
We report multi-band photometric imaging observations and Monte Carlo dust tail modelling of the interstellar comet 3I/ATLAS covering a wide range of heliocentric distances, from a…
The explosive growth of the Messier 74 galaxy. A galaxy doubling its size in less than a Gigayear
Ignacio Ruiz Cejudo, Ignacio Trujillo, Sergio Guerra Arencibia +3
Galaxy formation models predict that galaxies grow inside-out, becoming larger over time. While observations broadly support this paradigm, the nature and timescales of this growth…
The flash-ionised SN Ibn 2025kzr: H-free CSM formed during a precursor outburst 55 days prior to explosion
S. de Wet, G. Leloudas, D. A. H. Buckley +33
Type Ibn supernovae (SNe) are a class of interacting SNe characterised by narrow helium lines in their spectra. We present an extensive observational dataset of the Type Ibn SN 202…
Accessible does not mean exploitable: HiPERCAM reveals the ultra-fast rotation of 2022 OB
Miguel R. Alarcon, Javier Licandro, Miquel Serra-Ricart +2
2022 OB is a sub-10-metre Apollo-type near-Earth asteroid whose orbital configuration placed it among the most dynamically accessible small bodies in near-Earth space, motivati…
Spin Parameters and Shape Models of Near-Earth Asteroids (4660) Nereus, (21088) Chelyabinsk, (66146) 1998 TU3, and (297418) 2000 SP43
Javier Rodríguez Rodríguez, Enrique Díez Alonso, Santiago Iglesias Álvarez +8
We present our shape and rotational characterization of four near-Earth asteroids observed as part of the Visible NEAs Observations Survey. This work includes 61 new light curves o…
A High-Throughput AES-GCM Implementation on GPUs for Secure, Policy-Based Access to Massive Astronomical Catalogs
Samuel Lemes-Perera, Miguel R. Alarcon, Pino Caballero-Gil +1
The era of large astronomical surveys generates massive image catalogs requiring efficient and secure access, particularly during pre-publication periods where data confidentiality…
On the rotation of M-type asteroids: statistical evidence for higher rotation rates
Fernando Abarzuza, Noemí Pinilla-Alonso, Miquel Serra-Ricart +2
Rotational dynamics of asteroids carry important information about their internal structure, collisional history and material composition. This work investigates whether M-type ast…
