Dynamical mass of the Serpens intermediate-mass young stellar system EC\,95 with DYNAMO--VLBA
JazmÃn Ordóñez-Toro, Sergio A. Dzib, Laurent Loinard +8
We present dynamical mass measurements, obtained from multi-epoch Very Long Baseline Interferometry (VLBI) observations, for the young multiple stellar system EC\,95, located in th…
Spectroscopic study of globular and fuzzy clusters in Lenticular galaxy NGC 1023
Miguel A. López-SantamarÃa, Y. D. Mayya, Luis LomelÃ-Núñez +5
We here report the results from spectroscopic observations of a sample of 26 globular cluster (GC) and 21 faint fuzzy (FF) candidates in the lenticular galaxy NGC 1023 using the 10…
VLBA Detections in the Oph-S1 Binary System near Periastron Confirmation of its Orbital Elements and Mass
JazmÃn Ordóñez-Toro, Sergio A. Dzib, Laurent Loinard +7
Oph-S1 is the most luminous and massive stellar member of the nearby Ophiuchus star-forming region. Previous Very Long Baseline Array (VLBA) observations have shown it to be an int…
When Is a Bulge Not a Bulge? Revealing the Satellite Nature of NGC 5474's Bulge
Ray Garner, J. Christopher Mihos, F. Fabián Rosales-Ortega
A satellite galaxy of the nearby spiral M101, NGC 5474 has a prominent bulge offset from the kinematic center of the underlying star-forming disk that has gained attention in recen…
