Extragalactic globular cluster near-infrared spectroscopy: II. The stellar population synthesis model zero-point problem extends to the near-infrared
E. Eftekhari, A. Vazdekis, R. Riffel +5
Many recent studies have pointed out significant discrepancies between observations and models of stellar populations in the near-infrared (NIR). With current and future observing…
Extragalactic globular cluster near-infrared spectroscopy: I. Integrated near-infrared spectra of Centaurus A/NGC 5128
L. G. Dahmer-Hahn, A. L. Chies-Santos, E. Eftekhari +6
One way to constrain the evolutionary histories of galaxies is to analyse their stellar populations. In the local Universe, our understanding of the stellar population properties o…
Capivara: A Spectral-based Segmentation Method for IFU Data Cubes
Rafael S. de Souza, Luis G. Dahmer-Hahn, Shiyin Shen +7
We present capivara, a fast and scalable spectral-based segmentation package designed to study astrophysical properties within distinct structural components of galaxies. This spec…
Low surface brightness dwarf galaxies and their globular cluster populations around the low-density environment of our closest S0 NGC3115
Marco A. Canossa-Gosteinski, Ana L. Chies-Santos, Cristina Furlanetto +12
Understanding faint dwarf galaxies is fundamental to the development of a robust theory of galaxy formation on small scales. Since the discovery of a population of ultra diffuse ga…
Systematics in ETG Mass Profile Modelling: Strong Lensing & Stellar Dynamics
Carlos R. Melo-Carneiro, Cristina Furlanetto, Ana L. Chies-Santos
Strong gravitational lensing and stellar dynamics are independent and powerful methods to probe the total gravitational potential of galaxies, and thus, their total mass profile. H…
Systematic analysis of jellyfish galaxy candidates in Fornax, Antlia, and Hydra from the S-PLUS survey: A self-supervised visual identification aid
Yash Gondhalekar, Ana L. Chies-Santos, Rafael S. de Souza +22
We study 51 jellyfish galaxy candidates in the Fornax, Antlia, and Hydra clusters. These candidates are identified using the JClass scheme based on the visual classification of wid…
