  • Universidad Complutense de Madrid list 1

    A low dispersion objective-prism survey for low-redshift emission-line galaxies (ELGs) is being carried out by the University Complutense de Madrid with the Schmidt telescope at...
  • IRAS 1Jy sample of ultraluminous galaxies. II.

    An R and K' atlas of the IRAS 1 Jy sample of 118 ultraluminous infrared galaxies (ULIGs) was presented in a companion paper (our Paper I, Kim et al., 2002, Cat. ). The present...
  • IRAS 1Jy sample of ultraluminous galaxies. I.

    An imaging survey of the IRAS 1Jy sample of 118 ultraluminous infrared galaxies was conducted at optical (R) and near-infrared (K') wavelengths using the University of Hawaii...
  • 90 cepheid candidates nearby NGC 6814

    We present a Cepheid-based distance to the nearby Seyfert galaxy NGC6814 from Hubble Space Telescope observations. We obtained F555W and F814W imaging over the course of 12...
  • Exploring 6 AGN dusty torus models. II.

    This is the second in a series of papers devoted to exploring a set of six dusty models of active galactic nuclei (AGN) with available spectral energy distributions. These...
  • MIR view of polar dust emission in local AGNs

    Recent mid-infrared (MIR) interferometric observations have shown that in a few active galactic nuclei (AGNs) the bulk of the infrared emission originates from the polar region...
  • Broad H{beta} emission line in 102 Seyfert galaxies

    A sample of 102 local (0.02=<z=<0.1) Seyfert galaxies with black hole masses M_BH_>10^7^M_{sun} was selected from the Sloan Digital Sky Survey (SDSS) and observed using...
  • NGC4395 light curves. III.

    We present optical observations of the low-luminosity Seyfert 1 nucleus of NGC 4395, as part of a multiwavelength reverberation-mapping program. Observations were carried out...
  • Panchromatic SED of Herschel sources

    Combining far-infrared Herschel photometry from the PACS Evolutionary Probe (PEP) and Herschel Multi-tiered Extragalactic Survey (HerMES) guaranteed time programs with ancillary...
  • NGC253 near-infrared H_2_ emission

    Because of its large angular size and proximity to the Milky Way, NGC 253, an archetypal starburst galaxy, provides an excellent laboratory to study the intricacies of this...
  • Extended CO structures in NGC6240

    We present deep CO(1-0) observations of NGC6240 performed with the IRAM Plateau de Bure Interferometer (PdBI). NGC6240 is the prototypical example of a major galaxy merger in...
  • Circinus galaxy CRIRES observations

    We present new CRIRES spectroscopic observations of the Br{gamma} emission line in the nuclear region of the Circinus galaxy, obtained with the aim of measuring the black hole...
  • NGC 4151 line-continuum diagram sequences

    We present the first results of an 8-year spectroscopic monitoring of the Seyfert 1.5 galaxy NGC 4151 carried out with a CCD spectrograph at the 2.6-m Shajn Telescope of the...
  • NIR lines for AGN up to z~3

    Optical rest-frame spectroscopic diagnostics are usually employed to distinguish between star formation and active galactic nucleus (AGN) powered emission. However, this method...
  • KISS H{alpha} survey list 1

    The KPNO International Spectroscopic Survey (KISS) is a new objective-prism survey for extragalactic emission-line objects. It combines many of the features of previous slitless...
  • Catalog of NLS1s galaxies in 6dFGS survey

    We present a new accurate catalog of narrow-line Seyfert 1 galaxies (NLS1s) in the southern hemisphere from the Six-degree Field Galaxy Survey (6dFGS) final data release, which...
