[image: lIlustration of a gravitational lens] *1.September Telecon: Cosmology from Gravitational Lensing * NSN members: join us on *Thursday, September 25 at 6:00 pm Pacific Time * for an informative telecon with *Dr. Mandeep Gill* <http://www.slac.stanford.edu/~msgill/> of the Stanford Linear Accelerator Center (*SLAC*). His topic will be: *Cosmology from Gravitational Lensing*, or Professor Einstein Teaches us About the Cosmos through its Spacetime Curvature. Dr. Gill will take us through a tour through the universe of the very big and very small, and show us the links between particle physics on Earth and the warping of spacetime that we can see on very large scales in our universe. Slides and more information will be available shortly on our resource page here: http://bit.ly/nsnlensing . *Call-in Information* NSN members are invited to join the live telecon by calling the toll-free line: *1-888-455-9236 <1-888-455-9236>* Call up to 15 minutes before the telecon begins. An operator will answer and: - You will be asked for the passcode: *NIGHT SKY NETWORK* - You will be asked to give your *NAME* and the *CLUB* you belong to as well as the number of people listening with you. *About Dr. Mandeep Gill* *[image: Dr. Mandeep Gill, photo courtesy Stanford]* Dr. Mandeep Gill is an observational cosmologist and a memb er of the public affairs department at SLAC concentrating on gravitational weak lensing. In 2008 he was a postdoctoral research fellow at the Center for Cosmology and Particle Physics at the Ohio State University concentrating on gravitational weak lensing and determination of cosmological parameters from this technique. He earned his doctorate at UC Berkeley in 2004 in Experimental High Energy Particle Physics. In the summer of 2005 he visited the LHC at CERN in Geneva, Switzerland, and observed (one might even say was "awed by") the construction of the CMS and Atlas experiments. In a visiting position at Caltech in 2006 he was involved in a cosmology project involving second order weak lensing (and ultimately better dark matter distribution determination) of distant galaxy clusters. I wonder if we can set this up while at PVCC doing the Telescope Workshop, to listen to it during the workshop, howeverer, it begins at 6 and we aren't there until 7pm, maybe that won't work in our favor. -- Good friends are like stars.
