A search for millimetric emission from Gamma Ray Bursts
S. Ali, R. K. Schaefer, M. Limon +1
We have used the 2- year Differential Microwave Radiometer data from the COsmic Background Explorer (COBE) satellite to systematically search for millimetric (31 - 90 GHz) emission…
Millimetric Ground-based Observations of Cosmic Microwave Background Anisotropy
L. Piccirillo, B. Femenia, N. Kachwala +6
First results of a Cosmic Microwave Background (CMB) anisotropy experiment conducted at the Observatorio del Teide (Tenerife, Spain) are presented. The instrument is a four channel…
Pursuing Parameters for Critical Density Dark Matter Models
Andrew R Liddle, David H Lyth, R K Schaefer +2
We present an extensive comparison of models of structure formation with observations, based on linear and quasi-linear theory. We assume a critical matter density, and study both…
Cold Plus Hot Dark Matter Cosmology in the Light of Solar and Atmospheric Neutrino Oscillations
K. S. Babu, R. K. Schaefer, Q. Shafi
We explore the implications of possible neutrino oscillations, as indicated by the solar and atmospheric neutrino experiments, for the cold plus hot dark matter scenario of large s…
COBE Observations of the Microwave Counterparts of Gamma Ray Bursts
R. K. Schaefer, S. Ali, M. Limon +1
We have used the data from the COBE satellite to search for delayed microwave emission (31 - 90 GHz) from Gamma Ray Bursts (GRBs). The large beam of COBE is well matched…
Inflation and Large Scale Structure Formation After COBE
R. K. Schaefer, Q. Shafi
The simplest realizations of the new inflationary scenario typically give rise to primordial density fluctuations which deviate logarithmically from the scale free Harrison - Zeldo…
