The Narrow Line Region properties of ESO138-G001 unveiled by SOAR/SIFS observations
A. Rodríguez-Ardila, D. May, S. Panda +2
We study in detail the inner 600 pc of the Seyfert 2 galaxy ESO138-G001 by means of the SOAR Integral Field Spectrograph (SIFS) attached to the SOAR telescope. This source is known…
Reanalysis of neutron-capture elements in the benchmark r-rich star CS 31082-001
H. Ernandes, M. J. Castro, B. Barbuy +4
We revisit the abundances of neutron-capture elements in the metal-poor ([Fe/H]=-2.9) r-process-rich halo star CS 31082-001. Partly motivated by the development of the new near-ult…
Mapping the structure of the planetary 2:1 mean motion resonance. The TOI-216, K2-24, and HD27894 systems
Cristian Giuppone, Adrián Rodríguez, Viviam Alencastro +2
Mean motion resonances (MMR) are a frequent phenomenon among extrasolar planetary systems. Current observations indicate that many systems have planets that are close to or inside…
A Highly Magnified Star at Redshift 6.2
Brian Welch, Dan Coe, Jose M. Diego +26
Galaxy clusters magnify background objects through strong gravitational lensing. Typical magnifications for lensed galaxies are factors of a few but can also be as high as tens or…
Testing the key role of the stellar mass-halo mass relation in galaxy merger rates and morphologies via DECODE, a novel Discrete statistical sEmi-empiriCal mODEl
Hao Fu, Francesco Shankar, Mohammadreza Ayromlou +19
The relative roles of mergers and star formation in regulating galaxy growth are still a matter of intense debate. We here present our DECODE, a new Discrete statistical sEmi-empir…
The miniJPAS Survey: Detection of double-core Lyα morphology of two high-redshift (z>3) QSOs
P. T. Rahna, Zhen-Ya Zheng, Ana L. Chies-Santos +30
The Ly emission is an important tracer of neutral gas in a circum-galactic medium (CGM) around high-z QSOs. The origin of Lya emission around QSOs is still under debate which ha…
