Star formation and morphological trends in the Antlia cluster: Probing environmental influence out to 5R200
Ciria Lima-Dias, Antonela Monachesi, Gissel P. Montaguth +48
Galaxy evolution in dense environments such as clusters is strongly affected by environmental processes that can alter both morphology and star formation activity. We investigate t…
Kilometre-scale Jovian moon characterized for a potential JUICE flyby
Juan Luis Rizos, Jose Maria Gomez-Limon, Yucel Kilic +51
Jupiter's irregular satellites are thought to be relics of early Solar System planetesimals. However, their small sizes, large distances from Earth and close angular proximity to J…
Galaxy evolution in compact groups - III. Structural analysis of galaxies and dynamical state of non-isolated compact groups
Gissel P. Montaguth, Ana Laura O'Mill, Claudia Mendes de Oliveira +17
Compact Groups (CGs) of galaxies are dense systems where projected separations are comparable to their optical diameters. A subset - non-isolated CGs - are embedded within major st…
Historical Surveys to Rubin First Look: Absolute Colors of trans-Neptunian objects
Milagros Colazo, Alvaro Alvarez-Candal
We present a comprehensive photometric study of trans-Neptunian objects (TNOs) by combining data from SDSS, Col-OSSOS, DES, and the recent Rubin First Look (RFL) data. Our database…
A catalog of near-IR absolute magnitudes of Solar System small bodies
Alvaro Alvarez-Candal, Juan Luis Rizos, Milagros Colazo +5
Context. Phase curves of small bodies are useful tools to obtain their absolute magnitudes and phase coefficients. The former relates to the object's apparent brightness, while the…
Asteroid phase curves and phase coloring effect using the ATLAS survey data
Colazo Milagros, Dagmara Oszkiewicz, Alvaro Alvarez-Candal +3
We determined phase curves for 301,272 asteroids in the orange filter and 280,953 in the cyan filter from the latest ATLAS Solar System Catalog V2 (SSCAT-2). Among them, 3,345 and…
The S-PLUS Ultra-Short Survey: Photometric Re-calibration with the BEst STar Database
Xiaolu Li, Kai Xiao, Yang Huang +15
We present an independent validation and comprehensive re-calibration of S-PLUS Ultra-Short Survey (USS) DR1 12-band photometry using about 30,000--70,000 standard stars from the B…
A discussion on estimating small bodies taxonomies using phase curves results
Alvaro Alvarez-Candal
Upcoming large multiwavelength photometric surveys will provide a leap in our understanding of small body populations, among other fields of modern astrophysics. Serendipitous obse…
The S-PLUS Ultra-Short Survey: first data release
Hélio D. Perottoni, Vinicius M. Placco, Felipe Almeida-Fernandes +15
This paper presents the first public data release of the S-PLUS Ultra-Short Survey (USS), a photometric survey with short exposure times, covering approximately 9300 deg of t…
The multi-wavelength phase curves of small bodies: Phase coloring
Alvaro Alvarez-Candal
Context. Small bodies change their brightness due to different motives: Rotation along their axis or axes, combined with irregular shapes and/or changing surface properties, or cha…
Zero-phase angle asteroid taxonomy classification using unsupervised machine learning algorithms
M. Colazo, A. Alvarez-Candal, R. Duffard
We are in an era of large catalogs and, thus, statistical analysis tools for large data sets, such as machine learning, play a fundamental role. One example of such a survey is the…
Photometric and spectroscopic evidence for a dense ring system around Centaur Chariklo
R. Duffard, N. Pinilla-Alonso, J. L. Ortiz +7
In this work we aim to study if the variability in the absolute magnitude of Chariklo and the temporal variation of the spectral ice feature, even its disappearance in 2007, can be…
Mineralogical Characterization of Baptistina Asteroid Family: Implications for K/T Impactor Source
Vishnu Reddy, Jorge M. Carvano, Daniela Lazzaro +8
Bottke et al. (2007) linked the catastrophic formation of Baptistina Asteroid Family (BAF) to the K/T impact event. This linkage was based on dynamical and compositional evidence,…
Colors and taxonomy of Centaurs and Trans-Neptunian Objects
D. Perna, M. A. Barucci, S. Fornasier +6
The study of the surface properties of Centaurs and Trans-Neptunian Objects (TNOs) provides essential information about the early conditions and evolution of the outer Solar System…
