Spectral Line Variability in the Circumstellar Environment of the Classic al T Tauri Star SU Aurigae
J. M. Oliveira, B. H. Foing, Y. C. Unruh
SU Aurigae is a classical T Tauri star of spectral type G2. This star was one of the scientific targets of the MUSICOS 96 multi-site campaign that provided a wealth of high resolut…
Constraints on the Cosmological Parameters using CMB observations
Graca Rocha
This paper covers several techniques of intercomparison of Cosmic Microwave Background (CMB) anisotropy experiments and models of structure formation. It presents the constraints o…
The cloud-in-cloud problem for non-Gaussian density fields
Pedro P. Avelino, Pedro T. P. Viana
The cloud-in-cloud problem is studied in the context of the extension to non-Gaussian density fields of the Press-Schechter approach for the calculation of the mass function. As an…
Early detection of the optical counterpart to GRB 980329
J. Gorosabel, A. J. Castro-Tirado, A. Pedrosa +6
We report optical observations of the GRB 980329 error box which represent the second earliest detection of the GRB 980329 optical transient. We determine R = 23.7 0.5 mag on…
Does a varying speed of light solve the cosmological problems?
P. P. Avelino, C. J. A. P. Martins
We propose a new generalisation of general relativity which incorporates a variation in both the speed of light in vacuum (c) and the gravitational constant (G) and which is both c…
Python I, II, and III CMB Anisotropy Measurement Constraints on Open and Flat-Lambda CDM Cosmogonies
Graca Rocha, Radoslaw Stompor, Ken Ganga +4
We use Python I, II, and III cosmic microwave background anisotropy data to constrain cosmogonies. We account for the Python beamwidth and calibration uncertainties. We consider op…
Detection of Cosmic Microwave Background Structure in a Second Field with the Cosmic Anisotropy Telescope
Joanne C. Baker, Keith Grainge, M. P. Hobson +9
We describe observations at frequencies near 15 GHz of the second 2x2 degree field imaged with the Cambridge Cosmic Anisotropy Telescope (CAT). After the removal of discrete radio…
Galaxy Cluster Abundance Evolution and Cosmological Parameters
Pedro T. P. Viana, Andrew R. Liddle
We use the observed evolution of the galaxy cluster X-ray integral temperature distribution function between z=0.05 and z=0.32 in an attempt to constrain the value of the density p…
