نویسنده
چکیده
Detection of a large void (∼7 Mpc) is reported between the redshifts 2.16286 and 2.20748 in the Ly α forest of TOL 1038-2712. This void is centered near a foreground QSO TOL 1037-2704 which is at a distance ∼4.4 Mpc away from the void. The estimated probability for the void to occure by chance in front of the foreground QSO is few times 10 −3. Various implications of the void being produced by excess ionization due to foreground QSO are discussed.

A handful of new experiments aimed at measuring the asyet-undetected polarization of the cosmic background radiation (CBR) are described, with somewhat more detail given for three experiments with which the authors are associated.

TeV gamma rays from the blazar Markarian 501 have been detected with the University of Durham Mark 6 atmospherič Cerenkov telescope using the imaging technique at large zenith angles. Observations were made at zenith angles in the range 70 • − 73 • during 1997 July and August when Markarian 501 was undergoing a prolonged and strong flare.
