The Universidad Complutense de Madrid (UCM) survey is a long-term project aimed at finding and analyzing star-forming galaxies detected by their Ha emission in Schmidt objective-prism plates. The instrumental setup limits the volume of the universe surveyed to a redshift z = 0.045. So far we have discovered several hundred emission-line galaxies (ELGs)(More)
Luminous Compact Blue Galaxies (LCBGs) are high surface brightness starburst galaxies bluer than a typical SBc and with typical luminosities≈ L*, which are undergoing a major burst of star formation. LCBGs are the closest counterparts to the large population of starburst galaxies observed at high redshift, including Lyman-break galaxies at z≈2. However,(More)
The Sky Quality Meter (SQM) has become the most common device to track the evolution of the brightness of the sky from polluted regions to first class astronomical observatories. A vast database of SQM measurements already exists for many places in the world. Unfortunately, the SQM operates over a wide spectral band and its spectral response interacts with(More)
We present specific star formation rate (sSFR) radial profiles for a sample of 161 relatively face-on spiral galaxies from theGALEXAtlas of NearbyGalaxies. The sSFR profiles are derived fromGALEX and 2MASS (FUV K ) color profiles after a proper SFR calibration of the UV luminosity and K-band mass-to-light ratio are adopted. The (FUV K ) profiles were first(More)
In order to overcome the shortage of silicon feedstock that is currently affecting the photovoltaic industry, many efforts are being dedicated to the search of alternative substrates for solar cells. One of the possible solutions is to use low-cost substrates of upgraded metallurgical silicon, for which there are no supply issues. The solar cell is built on(More)
We have mapped the 12 CO J=1-0 and J=2-1 line emission in Mrk 86, one of the most metal-deficient Blue Compact Dwarf galaxies so far detected in 12 CO. The 12 CO emission is distributed in a horseshoe-like structure that follows the locus of the most recent star formation regions. The minimum in molecular-line emission corresponds to the position of an(More)
We present an analysis of the integrated properties of the stellar populations in the Universidad Complutense de Madrid (UCM) Survey of Hα-selected galaxies. In this paper, the first of a series, we describe in detail the techniques developed to model star-forming galaxies using a mixture of stellar populations, and taking into account the observational(More)
We present new near-infrared J and K imaging data for 67 galaxies from the Universidad Complutense de Madrid survey used to determine the SFR density of the local universe by Gallego et al. (1995). This is a sample of local star-forming galaxies with redshift lower than 0.045, and they constitute a representative subsample of the galaxies in the complete(More)
EMIR is a near-infrared, multi-slit camera-spectrograph under development for the 10m GTC on La Palma. It will deliver up to 45 independent R=3500-4000 spectra of sources over a field of view (FOV) of 6’x3’, and allow NIR (Z, J, H, K) imaging over a 6’x6’ FOV, with spatial sampling of 0.175”/pixel. The prime science goal of the instrument is to open Kband,(More)
Emission line galaxies are an invaluable tool for our understanding of the evolution of galaxies in the Universe. Imaging of deep fields with narrow-band filters allows not only the selection of these objects, but also to infer the line flux and the equivalent width of the emission line with some assumptions. The narrow-band filter technique provides(More)
