Discovery of GRB 020405 and its Late Red Bump
P. A. Price, S. R. Kulkarni, E. Berger +41
We present the discovery of GRB 020405 made with the Inter-Planetary Network (IPN). With a duration of 60 s, the burst appears to be a typical long duration event. We observed the…
The UNSW Extrasolar Planet Search: Methods and First Results from a Field Centred on NGC 6633
M. G. Hidas, M. C. B. Ashley, J. K. Webb +7
We report on the current status of the University of New South Wales Extrasolar Planet Search project, giving details of the methods we use to obtain millimagnitude precision photo…
Compositionality, stochasticity and cooperativity in dynamic models of gene regulation
R. Blossey, L. Cardelli, A. Phillips
We present an approach for constructing dynamic models for the simulation of gene regulatory networks from simple computational elements. Each element is called a ``gene gate'' and…
The Dark Side of ROTSE-III Prompt GRB Observations
S. A. Yost, F. Aharonian, C. W. Akerlof +22
We present several cases of optical observations during gamma-ray bursts (GRBs) which resulted in prompt limits but no detection of optical emission. These limits constrain the pro…
Exploring Broadband GRB Behavior During gamma-ray Emission
S. A. Yost, H. F. Swan, E. S. Rykoff +44
The robotic ROTSE-III telescope network detected prompt optical emission contemporaneous with the gamma-ray emission of Swift events GRB051109A and GRB051111. Both datasets have co…
Early-Time Observations of the GRB 050319 Optical Transient
R. M. Quimby, E. S. Rykoff, S. A. Yost +18
We present the unfiltered ROTSE-III light curve of the optical transient associated with GRB 050319 beginning 4 s after the cessation of gamma-ray activity. We fit a power-law func…
The Early Optical Afterglow of GRB 030418 and Progenitor Mass Loss
E. S. Rykoff, D. A. Smith, P. A. Price +13
The ROTSE-IIIa telescope and the SSO-40 inch telescope, both located at Siding Spring Observatory, imaged the early time afterglow of GRB 030418. In this report we present observat…
GRB 081008: from burst to afterglow and the transition phase in between
F. Yuan, P. Schady, J. L. Racusin +30
We present a multi-wavelength study of GRB 081008, at redshift 1.967, by Swift, ROTSE-III and GROND. Compared to other Swift GRBs, GRB 081008 has a typical gamma-ray isotropic equi…
Prompt Optical Detection of GRB 050401 with ROTSE-IIIa
E. S. Rykoff, S. A. Yost, H. A. Krimm +20
The ROTSE-IIIa telescope at Siding Spring Observatory, Australia, detected prompt optical emission from Swift GRB 050401. In this letter, we present observations of the early optic…
Detection of GRB 060927 at z = 5.47: Implications for the Use of Gamma-Ray Bursts as Probes of the End of the Dark Ages
A. E. Ruiz-Velasco, H. Swan, E. Troja +54
We report on follow-up observations of the GRB 060927 using the ROTSE-IIIa telescope and a suite of larger aperture ground-based telescopes. An optical afterglow was detected 20 s…
The DEEP Groth Strip Survey X: Number Density and Luminosity Function of Field E/S0 Galaxies at z < 1
Myungshin Im, L. Simard, S. M. Faber +7
We present the luminosity function and color-redshift relation of a magnitude-limited sample of 145 mostly red field E/S0 galaxies at z < 1 from the DEEP Groth Strip Survey (GSS).…
The Anomalous Early Afterglow of GRB 050801
E. S. Rykoff, V. Mangano, S. A. Yost +24
The ROTSE-IIIc telescope at the H.E.S.S. site, Namibia, obtained the earliest detection of optical emission from a Gamma-Ray Burst (GRB), beginning only 21.8 s from the onset of Sw…
ROTSE-III Observations of the Early Afterglow From GRB 030329
D. A. Smith, E. S. Rykoff, C. W. Akerlof +12
Using two identical telescopes at widely separated longitudes, the ROTSE-III network observed decaying emission from the remarkably bright afterglow of GRB 030329. In this report w…
A Search for Untriggered GRB Afterglows with ROTSE-III
