Equatorial spectrophotometric standards
Spectral energy distributions for 41 stars, 7-8mag, near the celestial equator (DE=+/-3{deg}) were obtained. The 3100-7600{AA} spectral range is studied with a spectral... -
Spectrophotometric standards near DE=+40{deg}
The second stage to compile a list of regional intermediate-brightness spectrophotometric standards has been completed. It includes the spectral energy distribution for 24 stars... -
Energy distribution of O9-B5 stars
The normal spectral energy distribution for spectral subtypes from O4 to O8 and O9 to B5 for luminosity classes V,IV and III are derived. Three photometrically uniform catalogs... -
Energy distribution of O5-O8 stars
The normal spectral energy distribution for spectral subtypes from O4 to O8 for luminosity classes V,IV and III are derived. Three photometrically uniform catalogs served as the... -
Primary Spectrophotometric Standards
A spectrophotometric catalog of 238 bright stars was compared with the Tyan Shan photometric catalog in the WBVR system. An analysis of the photometry of ten stars in four... -
Spectrophotometric Standards near the Pole
Absolute energy distributions for 13 circumpolar ({delta}>+85deg) stars forming a spectrophotometric version of the North Polar Spectrophotometric Sequence (NPSS) are... -
Far-UV Point Sources from FAUST
We list the photometric measurements of point sources made by the Far Ultraviolet Space Telescope (FAUST) when it flew on the ATLAS-1 space shuttle mission. The list contains... -
Galaxy clusters in the SDSS-DR5
Recent large-scale galaxy spectroscopic surveys, such as the Sloan Digital Sky Survey (SDSS), enable us to execute a systematic, relatively unbiased search for galaxy clusters.... -
Spectrophotometry of nearby field galaxies
We have obtained integrated and nuclear spectra as well as U, B, R surface photometry for a representative sample of 196 nearby galaxies. These galaxies span the entire Hubble... -
Extragalactic globular clusters
This is a collection of line indices in the Lick system (and others) for a collection of Galactic, M31, M33 and other globular clusters plus bright and dwarf galaxies observed... -
Gamma-ray bright blazars spectrophotometry
We present {gamma}-ray, X-ray, ultraviolet, optical, and near-infrared light curves of 33 {gamma}-ray bright blazars over 4 years that we have been monitoring since 2008 August... -
SHARDS: GOODS-N spectrophotometry survey
We present the Survey for High-z Absorption Red and Dead Sources (SHARDS), an ESO/GTC Large Program carried out using the OSIRIS instrument on the 10.4m Gran Telescopio Canarias... -
HST/WFC3 transit observation of GJ1214b
Capitalizing on the observational advantage offered by its tiny M dwarf host, we present Hubble Space Telescope/Wide Field Camera 3 (WFC3) grism measurements of the transmission... -
Galactic anticenter PNe and oxygen abundance
We have obtained spectrophotometric observations of 41 anticenter planetary nebulae (PNe) located in the disk of the Milky Way. Electron temperatures and densities, as well as... -
Red supergiants in M31
Red supergiants (RSGs) are a short-lived stage in the evolution of moderately massive stars (10-25M_{sun}_), and as such their location in the H-R diagram provides an exacting... -
Spectrophotometry in NGC 5253
We present echelle spectrophotometry of the blue compact dwarf galaxy NGC 5253 obtained with the VLT UVES. We have measured the intensities of a large number of permitted and... -
Spectrophotometry of 26 supergiants in the LMC
New spectrophotometric data for 3 galactic and 23 LMC F to G supergiants are presented. The wavelength range of the spectra is 3400 to 6400{AA}, the resolution about 10{AA}. The... -
Stellar content of NGC 346
Using CCD UBV photometry and spectroscopy, we have investigated the stellar content of NGC 346, the brightest H II region in the SMC. Spectra of 42 stars confirm that 33 are of... -
Optical and ultraviolet photometry of SN 2012fr
Extensive optical and UltraViolet (UV) observations of the type Ia supernova (SN Ia) 2012fr are presented in this paper. It has a relatively high luminosity, with an absolute... -
Spectrophotometry of 3CR lobe-dominated quasars
We present results from optical spectrophotometry of 19 of the 25 lobe-dominated quasars in the 3CR complete sample. The optical spectra were obtained with the Hale 5m telescope...
