First performance of the gems + gmos system. Part1. Imaging
Pascale Hibon, Vincent Garrel, Benoit Neichel +6
During the commissioning of the Gemini MCAO System (GeMS), we had the opportunity to obtain data with the Gemini Multi-Object Spectrograph (GMOS), the most utilised instrument at G…
A global view on the colliding-wind binary WR 147
Svetozar A. Zhekov, Blagovest V. Petrov, Toma V. Tomov +1
We present results from a global view on the colliding-wind binary WR 147. We analysed new optical spectra of WR 147 obtained with Gran Telescopio CANARIAS and archive spectra from…
The January 2015 outburst of a red nova in M31
Alexander Kurtenkov, Peter Pessev, Toma Tomov +19
M31N 2015-01a (or M31LRN 2015) is a red nova that erupted in January 2015 -- the first event of this kind observed in M31 since 1988. Very few similar events have been confirmed as…
Gems first science results
Benoit Neichel, Fabrice Vidal, Francois Rigaut +19
After 101 nights of commissioning, the Gemini MCAO system (GeMS) started science operations in December 2012. After a brief reminder on GeMS specificities, we describe the overall…
Chemical Abundances of the Highly Obscured Galactic Globular Clusters 2MASS GC02 and Mercer 5
Francisco Penaloza, Peter Pessev, Sergio Vasquez +3
We present the first high spectral resolution abundance analysis of two newly discovered Galactic globular clusters, namely Mercer 5 and 2MASS GC02 residing in regions of high inte…
GNOMOS: The Gemini NIR-Optical Multi Object Spectrograph
Ricardo P. Schiavon, Andy Adamson, Kristin Chiboucas +20
This paper is a response to a call for white papers solicited by Gemini Observatory and its Science and Technology Advisory Committee, to help define the science case and requireme…
Gemini Frontier Fields: Wide-field Adaptive Optics -band Imaging of the Galaxy Clusters MACS J0416.1-2403 and Abell 2744
Mischa Schirmer, Rodrigo Carrasco, Peter Pessev +4
We have observed two of the six Frontier Fields galaxy clusters, MACS J0416.1-2403 and Abell 2744, using the Gemini Multi-Conjugate Adaptive Optics System (GeMS) and the Gemini Sou…
Independent Study and Spectral Classification of a Sample of Poorly Studied High Proper Motion M-dwarf Candidate Stars
Cristina Cabello, Géza Csörnyei, Jaroslav Merc +2
We report an independent spectral classification of a sample of poorly studied M-dwarf candidate stars observed with the OSIRIS instrument at GTC. Our project was carried out as an…
The GeMS/GSAOI Galactic Globular Cluster Survey (G4CS) I: A Pilot Study of the stellar populations in NGC 2298 and NGC 3201
Stephanie Monty, Thomas H. Puzia, Bryan W. Miller +12
We present the first results from the GeMS/GSAOI Galactic Globular Cluster Survey (G4CS) of the Milky-Way globular clusters (GCs) NGC 3201 and NGC 2298. Using the Gemini South Adap…
Gemini multi-conjugate adaptive optics system review II: Commissioning, operation and overall performance
Benoit Neichel, François Rigaut, Fabrice Vidal +30
The Gemini Multi-conjugate Adaptive Optics System - GeMS, a facility instrument mounted on the Gemini South telescope, delivers a uniform, near diffraction limited images at near i…
The Brightening of Re50N: Accretion Event or Dust Clearing?
Hsin-Fang Chiang, Bo Reipurth, Josh Walawender +5
The luminous Class I protostar HBC 494, embedded in the Orion A cloud, is associated with a pair of reflection nebulae, Re50 and Re50N, which appeared sometime between 1955 and 197…
