Optical Spectroscopy of Type Ia Supernovae
T. Matheson, R. P. Kirshner, P. Challis +19
We present 432 low-dispersion optical spectra of 32 Type Ia supernovae (SNe Ia) that also have well-calibrated light curves. The coverage ranges from 6 epochs to 36 epochs of spect…
Ten Year Review of Queue Scheduling of the Hobby-Eberly Telescope
Matthew Shetrone, Mark E. Cornell, James R. Fowler +10
This paper presents a summary of the first 10 years of operating the Hobby-Eberly Telescope (HET) in queue mode. The scheduling can be quite complex but has worked effectively for…
Reconstructed Density and Velocity Fields from the 2MASS Redshift Survey
Pirin Erdogdu, Ofer Lahav, John P. Huchra +13
We present the reconstructed real-space density and the predicted velocity fields from the Two Mass Redshift Survey (2MRS). The 2MRS is the densest all-sky redshift survey to date…
The Dipole Anisotropy of the 2mass Redshift Survey
P. Erdogdu, J. P. Huchra, O. Lahav +14
We estimate the flux weighted acceleration on the Local Group (LG) from the near-infrared Two Micron All Sky Redshift Survey (2MRS). The near-infrared flux weighted dipoles are ver…
UBVRI Light Curves of 44 Type Ia Supernovae
Saurabh Jha, Robert P. Kirshner, Peter Challis +2
We present UBVRI photometry of 44 type-Ia supernovae (SN Ia) observed from 1997 to 2001 as part of a continuing monitoring campaign at the Fred Lawrence Whipple Observatory of the…
The Dipole Anisotropy of the 2 Micron All-Sky Redshift Survey
P. Erdogdu, J. P. Huchra, O. Lahav +14
We estimate the acceleration on the Local Group (LG) from the Two Micron All Sky Redshift Survey (2MRS). The sample used includes about 23,200 galaxies with extinction corrected ma…
GRB 021004: a Massive Progenitor Star Surrounded by Shells
Bradley E. Schaefer, C. L. Gerardy, P. Hoflich +13
We present spectra of the optical transient of GRB021004 obtained with the Hobby-Eberly telescope starting 15.48, 20.31 hours, and 4.84 days after the burst and a spectrum obtained…
Clusters of galaxies in the local universe
C. S. Kochanek, Martin White, J. Huchra +4
We use a matched filter algorithm to find and study clusters in both N-body simulations artificially populated with galaxies and the 2MASS survey. In addition to numerous checks of…
The K-Band Galaxy Luminosity Function
C. S. Kochanek, M. A. Pahre, E. E. Falco +6
We measured the K-band luminosity function using a complete sample of 4192 morphologically-typed 2MASS galaxies with 7 < K < 11.25 mag spread over 2.12 str. Early-type (T < -0.5) a…
2MASS Extended Sources in the Zone of Avoidance
T. H. Jarrett, T. Chester, R. Cutri +4
The Two Micron All Sky Survey (2MASS) is now underway and will provide a complete census of galaxies as faint as 13.5 mag (3 mJy) at 2.2 microns for most of the sky, and ~12.1 mag…
The Northern ROSAT All-Sky (NORAS) Galaxy Cluster Survey I: X-ray Properties of Clusters Detected as Extended X-ray Sources
H. Boehringer, W. Voges, J. P. Huchra +11
In the construction of an X-ray selected sample of galaxy clusters for cosmological studies, we have assembled a sample of 495 X-ray sources found to show extended X-ray emission i…
