We present preliminary results of an on going program to study Lyman Alpha Emitters, Lyman Break Galaxies, and Quasars at high redshift with the OSIRIS...

In this work we discuss the detection of Ly-α emitters (LAEs) through the gravitational amplification effect due to the mass in the core of the cluster of...

Review of the book: Landscapes, Skyscapes, Archaeoastronomy Skyscapes: The Role and Importance of the Sky in Archaeology. Edited by Fabio Silva and Nicholas...

Large amplitude oscillations (LAO) are often detected in filaments. Their origin has been associated with shock waves or to interaction with eruptions and jets...

The N = Z 44Ti* nucleus has been populated in Fusion Evaporation process at very high excitation energies and angular momenta using two entrance channels with...

Delta (δ) sunspots sometimes host fast photospheric flows along the central magnetic polarity inversion line (PIL). Here we study the strong Doppler shift...

We discuss a number of interesting questions that arise from studies of extended absorbers observed in high redshift radio-galaxies. We propose to carry out 2-D...
