We have used the first matched set of GALEX and SDSS data to investigate the properties of a sample of 74 nearby galaxies with far-ultraviolet luminosities chosen to overlap the luminosity range of...

The UV Galaxy Luminosity Function in the Local Universe from GALEX Data (2004)

Wyder, Ted K., Treyer, Marie A., Milliard, Bruno, Schiminovich, David, Arnouts, Stéphane, Budavári, Tamás, ...

We present the results of a determination of the galaxy luminosity function at ultraviolet wavelengths at redshifts of $z=0.0-0.1$ from GALEX data. We determined the luminosity function in the GALEX...

Number Counts of GALEX Sources in FUV (1530A) and NUV (2310A) Bands (2004)

Xu, C. Kevin, Donas, Jose, Arnouts, Stephane, Wyder, Ted K., Seibert, Mark, Iglesias-Paramo, Jorge, ...

Number Counts of galaxies in two GALEX bands (FUV: 1530A and NUV: 2310A, both in AB magnitudes) are reported. They provide for the first time in the literature homogeneously calibrated number counts...

The Galaxy Evolution Explorer: A Space Ultraviolet Survey Mission (2004)

Martin, D. Christopher, Fanson, James, Schiminovich, David, Morrissey, Patrick, Friedman, Peter G., Barlow, Tom A., ...

We give an overview of the Galaxy Evolution Explorer (GALEX), a NASA Explorer Mission launched on April 28, 2003. GALEX is performing the first space UV sky-survey, including imaging and grism...

The Star Formation Rate Function of the Local Universe (2004)

Martin, D. Christopher, Seibert, Mark, Buat, Veronique, Inglesias-Paramo, Jorge, Barlow, Tom A., Bianchi, Luciana, ...

We have derived the bivariate luminosity function for the far ultraviolet (1530Angstroms) and far infrared (60 microns). We used matched GALEX and IRAS data, and redshifts from NED and PSC-z. We have...

Quasar Evolution and the Baldwin Effect in the Large Bright Quasar Survey (2001)

Green, Paul J., Forster, Karl, Kuraszkiewicz, Joanna

From a large homogeneous sample of optical/UV emission line measurements for 993 quasars from the Large Bright Quasar Survey (LBQS), we study correlations between emission line equivalent width and...

Emission Line Properties of the Large Bright Quasar Survey (2000)

Forster, Karl, Green, Paul J., Aldcroft, Thomas L., Vestergaard, Marianne, Foltz, Craig B., Hewett, Paul C.

We present measurements of the optical/UV emission lines for a large homogeneous sample of 993 quasars from the Large Bright Quasar Survey. Our largely automated technique accounts for continuum...

The X-ray spectra and spectral variability of intermediate type Seyfert galaxies: ASCA observations of NGC 4388 and ESO 103-G35 (1999)

Forster, Karl, Leighly, Karen M., Kay, Laura E.

The X-ray spectra of two intermediate type Seyfert galaxies are investigated using ASCA observations separated by more than a year. Both NGC 4388 and ESO 103-G35 exhibit strong, narrow Fe K alpha...

X-ray properties of intermediate and narrow-line type 1 Seyfert galaxies (1999)

Forster, Karl

The soft X-ray properties of two samples of Active Galactic Nuclei (AGN) are investigated using ROSAT PSPC and ASCA observations. A large sample of optically selected narrow-line type 1 Seyfert...

Optical and X-ray Spectroscopy of 1E 0449.4-1823: Demise of the original type 2 QSO (1998)

Halpern, Jules P., Eracleous, Michael, Forster, Karl

New optical spectra of the original narrow-line quasar 1E 0449.4-1823 show that it now has broad emission lines of considerable strength, eliminating it as a "type 2 QSO" candidate. We suggest that...

Evidence for Relativistic Outflows in Narrow-line Seyfert 1 Galaxies (1997)

Leighly, Karen M., Mushotzky, Richard F., Nandra, Kirpal, Forster, Karl

We report the observation of features near 1 keV in the ASCA spectra from three ``Narrow Line Seyfert 1'' (NLS1) galaxies. We interpret these as oxygen absorption in a highly relativistic outflow. If...

Extreme X-ray Variability In The Narrow-Line QSO PHL 1092 (1996)

Forster, Karl, Halpern, Jules P.

A ROSAT observation of the narrow-line Fe II QSO PHL 1092 shows rapid variability that requires an efficiency of at least 0.13, exceeding the theoretical maximum for an accretion disk around a...
