... Astrophysics Group . ... Exploring the Cosmic Dawn . ... Cosmic reionization corresponds to the epoch in which the first stars€а and black holes reionize the neutral intergalactic medium (IGM) that€аpervades the Universe following recombination, within a few hundred€аmillion years of the Big Bang. The epoch of reionization, and the€аpreceding ?dark ages? prior to the formation of the first stars,€аrepresent the last unexplored phases of cosmic evolution to be tested€аand explored. ...

Likely Impact Sites of Large Fragments of the Tunguska Cosmic Body . ... Kulik. Kulik schematized the tree fall around the Cranberry Hole and at the Southern Bog in order to elucidate the possible location of meteorite fragments. ... We consider that it is necessary to verify the Kulik proposal and to perform at first georadar investigations in the Suslov and Cranberry holes and then drill in the craters to find possible meteorite fragments. ...
