  • 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...
  • 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...
  • 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...
  • 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...
  • CALSPEC: WFC3 infrared grism spectrophotometry

    The collections of spectral energy distributions (SEDs) in the Hubble Space Telescope (HST) CALSPEC database are augmented by 19 infrared (IR) SEDs from Wide Field Camera 3...
  • 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...
  • Precision spectrophotometry at the level of 0.1%

    Accurate relative spectrophotometry is critical for many science applications. Small wavelength-scale residuals in the flux calibration can significantly impact the measurements...
  • 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...
  • Absolute flux distribution of BD +17 4708

    Secondary flux standards are established by measuring their brightness relative to primary standard stars. The Hubble Space Telescope (HST) primary standards are the three...
  • Spectrophotometry in open clusters

    Spectrophotometry is presented for 237 stars in 7 nearby open clusters: Hyades, Pleiades, Alpha Persei, Praesepe, Coma Berenices, IC 4665, and M39. The observations were taken...
  • BATC Color Survey of M67

    The authors present nine color CCD intermediate-band spectrophotometry of a two square degree field centered on the old open cluster M67, from 3890 Angstroms to nearly 1 micron....
  • HII galaxies spectrophotometric catalogue

    We present a spectrophotometric catalogue of 425 emission line galaxies discovered in objective prism surveys for which we derived redshifts, emission line intensities,...
  • Library of Spectra (0.5 to 2.5um) of Cool Stars

    The present catalogue contains 182 low resolution optical spectra, 145 medium resolution (R~1100) near-IR spectra, and 112 merged optical+near-IR spectra that range from about...
  • Sample of starburst nucleus galaxies

    This paper presents optical long-slit spectroscopic observations of 105 barred Markarian IRAS galaxies. These observations are used to determine the spectral type (starburst or...
