50th Anniversary of the Discovery of Optical Pulsations of the Crab Nebula Pulsar

The optical pulsations of the Crab Nebula Pulsar were discovered 50 years ago by Stewardites John Cocke, Mike Disney and Don Taylor using the Steward 36" telescope on Kitt Peak. On Jan 14  (the link is a blowup of the picture) we celebrated the anniversary, bringing John Cocke to Tucson to talk about what happened in 1969, and having Feryal Ozel give a more current perspective. A link to the podcast is HERE.

Three Faculty Win Awards

Professor Robert Kennicutt, Ass't Professor Erika Hamden, and Mirror Lab Project Scientist Buddy Martin have recently been recognized with awards.

Rob, who recently rejoined us after a decade in Cambridge, UK, has won two recent awards. The first is from the National Academy of Sciences and is called the 2019 NAS Award for Scientific Reviewing. The second is from the RAS, one of the 2019 Gold Medals of the Royal Astronomical Society. The UA press release can be found HERE.

Assistant Professor Erika Hamden was recently named a TED2019 Fellow. You can read the press release HERE

Faculty member Hubert (Buddy) Martin, Project Scientist of the Mirror Polishing Program at the Richard F. Caris Mirror Lab, received the SPIE's A.E. Conrady Award. We quote the citation here: "Dr. Buddy Martin has been awarded the A.E. Conrady Award in Optical Engineering for his contributions to the polishing of large mirrors, including those for the GMT. Dr. Martin has been the guiding hand in the polishing of the GMT mirrors."

Paola Pinilla Receives a 2018 Sofja Kovalevskaja Award of the Alexander von Humboldt Foundation

Steward Postdoc Paola Pinilla has received a 2018 Sofja Kovalevskaja Award of the Alexander von Humboldt Foundation. Paola is at center bottom of the image on the award page. Paola will leave for Germany in Summer 2019, and will have the funding to create a research group at the Max Planck Institute for Astronomy, Heidelberg, Planet and Star Formation Department, for a five-year period. Congratulations, Paola.

Protoplanetary Disks and Planets in Taurus

An international team lead by Feng Long (Peking University) and Paola Pinilla (Steward/University of Arizona), have obtained for the first time an unbiased ALMA survey of 32 protoplanetary disks in the Taurus star forming region, which spans a wide range of properties (e.g., millimeter brightness). In this sample, about 40% of the disks show concentric rings and gaps around young stars, confirming the commonality of these features. These rings and gaps give indirect evidence of planets being formed in their nascent environment. Interestingly, the morphology of these structures suggests that embedded super-Earths and Neptunes are the most likely possibility to explain these rings/gaps, in line with the most common type of planets discovered so far. The UA of Arizona press release can be found HERE. The scientific paper was published in the Astrophysical Journal HERE

Professor Lucy Ziurys Wins the 2019 Laboratory Astrophysics Prize of the AAS

Astronomy Dept./Steward Observatory and Chemistry Dept. Professor Lucy Ziurys has been honored by the American Astronomical Society. She has been awarded their 2019 Laboratory Astrophysics Prize. You can read the press release HERE

"The Laboratory Astrophysics Prize is presented, normally on an annual basis, to an individual who has made significant theoretical or experimental contributions to laboratory astrophysics over an extended period of time. The prize includes a cash award, a framed certificate, and an invited lecture by the recipient at a meeting of the Laboratory Astrophysics Division."

Congratulations, Dr Ziurys!
