Searching for a predicted metallicity variation in the type II globular cluster NGC 362 = Buscando una variación de metalicidad predicha en el cúmulo globular de tipo II NGC 362.
(Universidad de Concepción, Facultad de Ciencias Físicas y Matemáticas, Departamento de Astronomía., 2021)
According to Milone et al. (2017), NGC 362 is a rare Type II Galactic globular cluster,
showing a complex pseudo two-color diagram or ’Chromosome Map’ based on their
HST UV Legacy photometry. The clear separation of its ...
Formation imprints in the kinematics of the Milky Way globular cluster system
(IOP Publishing, 2019-07)
We report results on the kinematics of Milky Way (MW) globular clusters (GCs) based on updated space velocities for nearly the entire GC population. We found that a 3D space with the semimajor axis, the eccentricity, and ...
Analysis of the physical nature of 22 New VVV Survey Globular Cluster candidates in the Milky Way bulge
(Wiley Blackwell Publishing, Inc, 2019-08)
In order to characterize 22 new globular cluster (GC) candidates in the Galactic bulge, we present their colour-magnitude diagrams (CMDs) and Ks-band luminosity functions (LFs) using the near-infrared VVV database as well ...
Simulating the spatial distribution and kinematics of globular clusters within galaxy clusters in illustris
(Oxford University Press, 2020-04)
We study the assembly of globular clusters (GCs) in 9 galaxy clusters using the cosmological simulation Illustris. GCs are tagged to individual galaxies at their infall time. The tidal removal of GCs from their galaxies ...
Numerical estimates of the accretion rate on to intermediate-mass black holes
(Wiley Blackwell Publishing, Inc, 2013-04)
The existence of intermediate-mass (∼103 M⊙) black holes (IMBHs) in the centre of glob- ular clusters has been suggested by different observations. The X-ray sources observed in NGC 6388 and in G1 in M31 could be interpreted ...
