Rewarding Lunar Eclipse

On the night 7-8th October, the USA was fortunate to witness a total lunar eclipse and blood moon eclipse. This was the second in a series of four total lunar eclipses (the next will be in April 2015), and Milwaukeeans flocked to the UWM planetarium to witness this event. Jean Creighton, director of the Manfred Olsen Planetarium, highlights this spectacle.

Coffee, with a dash of Astrophysics!

Since the beginning of September a team of postdocs and grad students from the CGCA have been delighting local Milwaukeans with an informal lecture series - CoffeeShop Astrophysics. Taking place in a local coffeeshop, the group discusses hot topics in astrophysics with the local community. Lectures have included 'the big bang' and 'live fast, die young; the lifecycle of stars'. There are more to come!

Identity Management Team from the CGCA Participate in Pilot Project with Internet2's InCommon

A new pilot scheme between Internet2's InCommon and the identity management team from the Leonard E. Parker Center for Gravitation, Cosmology and Astrophysics (CGCA) will allow astronomers from across the world to use their local university credentials to access three UWM-based services, all services for the Laser Interferometer Gravitational-Wave Observatory (LIGO). This new approach will not only streamline the access process, but will also save much time and effort for the identity management staff who would otherwise have to create and maintain separate usernames and passwords for hundreds of researchers.

Summer Studies in the CGCA

This year there have been a lot of advances by corporations such as Google and IBM in teaching machines to think like people. A self-organized set of students collaborated over the past few months to learn techniques in astronomical statistics, data mining and machine learning. The idea was generated by group of Madison students and propelled forward by individuals here eager to learn from one another.

UWM Astronomy Club Students Receive Training in Pulsar Searching at World’s Largest Steerable Radio Dish

Several UWM physics students, CGCA postdoctoral researchers, and CGCA professors are members of the Green Bank North Celestial Cap (GBNCC) pulsar survey. The GBNCC collaboration is searching for pulsars in all parts of the sky that can be observed by the Green Bank Telescope (GBT) in West Virginia. The GBT is the largest steerable radio telescope in the world; the famous Arecibo Telescope in Puerto Rico is larger, but cannot be steered.

Postdoctoral Researchers Wow the Public with their Planetarium Lectures

This month, two CGCA postdoctoral researchers shared their research interests with a public audience during AstroBreak in the Manfred Olson Planetarium. The public lectures lasted 15 minutes, and were followed by 10-15 minutes of a Q&A session for the audience. After the lecture, the audience enjoyed a brief planetarium show given by Dr. Jean Creighton.

White Dwarfs Are Cool: CGCA Astronomer Involved in Detecting One of the Coolest, Dimmest Stellar Corpses Yet Seen

A team of astronomers -- including CGCA professor David Kaplan -- may have identified the coldest and dimmest specimen yet discovered among a class of objects called white dwarfs. If true, this remnant of a stellar death would probably be made of crystallized carbon, amounting basically to a gargantuan diamond floating in the cosmos.

WIYN keeping an eye on comet ISON

Comet ISON made an appearance in our skies during 2013 as it hurtled through our solar system, passing extremely close the Sun. Ralf Kotulla, a postdoctoral research associate within the CGCA, spent a little time during a joint UW-Milwaukee/UW-Madison observing run on the WIYN telescope to take advantage of this passing comet and captured beautiful images, one of which is now a finalist in the NSFs comet ISON photo contest (vote for Ralf's entry).
