IAC astronomers find one of the first stars formed in the Milky Way
Researchers at the Instituto de Astrofísica de Canarias (IAC) have identified, using the Gran Telescopio de Canarias (GTC) a star which is a key to the...
IAC-pop: Finding the Star Formation History of Resolved Galaxies
IAC-pop is a code designed to solve the star formation history (SFH) of a complex stellar population system, like a galaxy, from the analysis of the color...
Identification of a Group III CEMP-no Star in the Dwarf Spheroidal Galaxy Canes Venatici I
CEMP-no stars, a subclass of carbon-enhanced metal-poor (CEMP) stars, are one of the most significant stellar populations in galactic archeology, because they...
Identification of Near-infrared [Se iii] and [Kr vi] Emission Lines in Planetary Nebulae
We identify [Se iii] 1.0994 μm in the planetary nebula (PN) NGC 5315 and [Kr vi] 1.2330 μm in three PNe from spectra obtained with the Folded-Port InfraRed...
Identifying Sagittarius Stream Stars by Their APOGEE Chemical Abundance Signatures
The SDSS-IV Apache Point Observatory Galactic Evolution Experiment (APOGEE) survey provides precise chemical abundances of 18 chemical elements for ∼176,000 red...
Identifying two groups of massive stars aligned in the l 38° Galactic direction
Context. Recent near-infrared data have contributed to unveiling massive and obscured stellar populations in both new and previously known clusters in our...
IGAPS: the merged IPHAS and UVEX optical surveys of the northern Galactic plane
The INT Galactic Plane Survey (IGAPS) is the merger of the optical photometric surveys, IPHAS and UVEX, based on data from the Isaac Newton Telescope (INT)...
Impact of Distance Determinations on Galactic Structure. II. Old Tracers
Here we review the efforts of a number of recent results that use old tracers to understand the build up of the Galaxy. Details that lead directly to using...
