Why the Northern Hemisphere Needs a 30-40 m Telescope and the Science at Stake: Northern Local Star-forming Dwarf Galaxies. Analogues of the First Galaxies and Probes of the Cosmic Metallicity Scale
C. Esteban, J. M. Vilchez, J. GarcÃa-Rojas +15
Star-forming dwarf galaxies in the local Universe, especially extremely metal-poor ones, can be considered analogous to early galaxies of the Epoch of Reionization (z >= 6). Curren…
Globules and pillars in Cygnus X IV. Velocity-resolved [OI] 63 mu map of a peculiar proplyd-like object
N. Schneider, S. Dannhauer, E. Keilmann +14
We investigated an isolated, globule-shaped object (0.37x0.11 pc), located near the centre of the Cygnus OB2 cluster and named proplyd #7 in optical observations. The source can be…
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…
Spectroscopic and photometric confirmation of 3 globular and 14 intermediate-age clusters in the Irr II galaxy NGC3077
Pedro A. Ovando Ramirez, Y. D. Mayya, Lino H. Rodriguez-Merino +4
We present the results from spectroscopic and photometric analysis of 17 globular cluster (GC) candidates in the Irr II galaxy NGC 3077. The GC candidates were selected on the Hubb…
