Understanding Galaxy Formation and Evolution
V. Avila-Reese
The old dream of integrating into one the study of micro and macrocosmos is now a reality. Cosmology, astrophysics, and particle physics intersect in a scenario (but still not a th…
Discovery of a tight correlation among the prompt emission properties of long Gamma Ray Bursts
C. Firmani, G. Ghisellini, V. Avila-Reese +1
We report the discovery of a correlation among three prompt emission properties of GRBs. These are the isotropic peak luminosity L_iso, the peak energy of the time-integrated promp…
The Hubble diagram extended to z>>1: the gamma-ray properties of GRBs confirm the Lambda-CDM model
C. Firmani, V. Avila-Reese, G. Ghisellini +1
Tight constraints on cosmological parameters can be obtained with standard candles spanning a range of redshifts as large as possible. We propose to treat SN Ia and long Gamma-Ray…
The Effects of Interactions on the Structure and Morphology of Elliptical/Lenticular galaxies in Pairs
H. Hernandez-Toledo, V. Avila-Reese, J. R. Salazar-Contreras +1
We present a photometric and structural analysis of 42 E/S0 galaxies in (E/S0 + S) pairs observed in the BVRI color bands. We empirically determine the effects of interactions on t…
HD molecule and search for early structure-formation signatures in the Universe
R. Nunez-Lopez, A. Lipovka, V. Avila-Reese
Possible detection of signatures of structure formation at the end of the 'dark age' epoch (z~40-20) is examined. We discuss the spectral-spatial fluctuations in the CMBR temperatu…
