A micronova burst in the intermediate polar IGR J17014-4306
Alexandre S. Oliveira, D. C. Souza, G. J. M. Luna +1
We report the detection of a short optical burst in TESS data of IGR J17014-4306, the eclipsing intermediate polar with the longest known orbital period. The burst lasts 1.56 d and…
The S-PLUS Fornax Project (S+FP): An extragalactic catalog covering 5 virial radii around NGC 1399 with galaxy properties
R. F. Haack, A. V. Smith Castelli, L. Sodré +22
Observational extragalactic catalogs over wide sky areas are essential for uncovering the large-scale structure of the Universe. They allow, among others, cosmological studies and…
Impact of AGN and nuclear star formation on the ISM turbulence of galaxies: Insights from JWST/MIRI spectroscopy
Rogemar A. Riffel, Luis Colina, José Henrique Costa-Souza +31
Active galactic nuclei (AGN), star formation (SF), and galaxy interactions can drive turbulence in the gas of the ISM, which in turn plays a role in the SF within galaxies. The imp…
Targeting cluster galaxies for the 4MOST CHANCES Low-z sub-survey with photometric redshifts
Hugo Méndez-Hernández, Ciria Lima-Dias, Antonela Monachesi +54
The evolution of galaxies is shaped by both internal processes and their external environments. Galaxy clusters and their surroundings provide ideal laboratories to study these eff…
The rings of (2060) Chiron: Evidence of an evolving system
C. L. Pereira, F. Braga-Ribas, B. Sicardy +54
The centaur (2060) Chiron has long been a candidate for hosting material in orbit, based on occultation and photometric and spectroscopic data. Here, we present a multichord stella…
Ionized Gas Outflows and Shock-Heated Emission in the Highly Inclined Active Galaxy CGCG 012-070
Lucas Ramos Vieira, Rogemar A. Riffel, Rogério Riffel +3
Active Galactic Nuclei (AGNs) exhibit excess mid-infrared H emission compared to star-forming galaxies, likely driven by outflows and shocks inferred from integrated spectra. W…
