KIPAC Newsletter #5 (December 2, 2014)

Dear KIPACers,

Welcome back to our newsletter. Lots of exciting things going at the Institute as always. This one comes just in time before our holiday party on Friday that I hope you all can make it to. We welcome a lot of new people and we can be very happy about all the progress we have seen in the last few months. Please also have a look at all the upcoming meetings we will host here and do think about other programs and workshops you might want to host here.

Warmest wishes and see you Friday,
Tom
for the KIPAC management team
Greg, Pat, Risa, Ziba

News items:

  • We are very happy for our colleagues Richard Partridge, Blas Cabrera and the SuperCDMS team, and Tom Shutt, Dan Akerib, Bill Wisniewski, and Blair Ratcliff and the LZ team: both teams were successful in the recent DOE’s Dark Matter experiment downselect. They are working hard to provide the most stringent limits on how much dark matter may interact with regular matter.
  • The Gemini Planet Imager had first light in November 2013. The team has participated in five commissioning and performance-verification observing runs. Two science papers were led by KIPAC authors, one on first light and the orbit of Beta Pictoris b (Macintosh et al 2014) and one on the spectra of the HR8799c and d planets. Two papers by other team members covered polarimetry of the disk of dust orbiting HR4796 (Perrin et al 2014) and the spectrum of Beta Pictoris b (Chilcote et al 2014.) Community science verification also started in 2014. Overall GPI has had the most successful first year of any Gemini instrument. Now that GPI is commissioned, the team has begun a large-scale survey. Over 3 years, they will examine 600 young nearby stars to search for giant exoplanets and dusty debris disks. Simulations indicate that 20-40 planets could be discovered and characterized. Over the summer, undergraduate students Loren Amdahl-Culleton and Kyana van Houten worked with the group on analyzing GPI performance testing data, and simulating future observations with GPI or WFIRST.  Professor Macintosh is also active in the science planning for a possible coronagraphic instrument on the WFIRST-AFTA space telescope, and will be setting up a laboratory for advanced adaptive optics technology.
  • LSST received its official federal construction start on August 1, when the NSF authorized the LSST project for construction. This was followed later in August by an LSST project and community meeting in Phoenix. The LSST Camera Project successfully passed a major milestone on November 6-7: the DOE Critical Decision 2 (CD2) review. The LSST project has been launched!
  • The LSST Dark Energy Science Collaboration (DESC) meeting was held in Philadelphia from June 17-19.   The next collaboration meeting will be held at SLAC, February 3-5, with a one-day "LSST Cosmology School" on Monday 2nd February, aimed at new DESC members.
  • An LSST@SLAC steering committee has been formed. Members are Steve Allen (chair), Pat Burchat, Richard Dubois, Steve Kahn, Steve Ritz, Aaron Roodman, Risa Wechsler. One of their first initiatives has been the organization of a new series of LSST@SLAC “micro-workshops” to draw a broad set of colleagues from Stanford and SLAC to hear about ongoing local LSST work. These take place three times per quarter, on Fridays at SLAC from 11:30 to 12:30.  Everyone is invited to join!  The next meetings will be on January 23, February 13, and March 13, 2015.
  • Astro-H is on track for launch in late 2015.  This Japanese-led satellite-based mission is aimed at studies of celestial sources over a broad X-ray band;  the US scientists are extensively involved in preparing flight hardware and in planning of the mission.  It will feature a novel, high-resolution X-ray spectrometer relying on a measurement of the energy of an incoming X-ray by measuring the temperature change in the sensor resulting from an absorption of the  photon.  The main goals of the mission will be studies of galaxy clusters, supernova remnants, and accreting compact sources.  The instruments are being integrated into the satellite, and this includes extensive testing of all subsystems.  Steve Allen, Greg Madejski, Norbert Werner, and Irina Zhuravleva are members of the Astro-H Science Working Group.  
  • DESI (Dark Energy Spectroscopy Instrument) successfully passed the DOE Critical Decision 1 (CD1) Review September 9-11. The project is proceeding well and is on track to be taking survey data in 2019.  A precursor imaging survey called DECal began this fall; it will observe 6600 square degrees with the Dark Energy Camera and will have regular public data releases. The next DESI collaboration meeting, to be focused on developing a Science Readiness Plan, will be held at SLAC, January 9-10.  KIPAC members who have an interest in getting involved in DESI should contact Risa Wechsler (Co-Spokesperson for the DESI Collaboration).
  • Mandeep Gill has a new role that includes facilitating and publishing the KIPAC blogs.  Please contact him if you would like to contribute to our blog articles.
  • Lori White is working with KIPAC as a freelance writer, interviewing and writing a  series of blogs on KIPAC alumni. The first one about Matthew Turk is already online.
  • Kahnfest will take place on January 29 and 30th 2015.  Stanford/KIPAC/SLAC are organizing a conference in honor of Steve Kahn's 60th birthday. The symposium will cover a broad range of astrophysical topics enabled by new technology, from X-ray to gravitational waves to LSST. If  you have not done so already, please visit http://kipac.stanford.edu/kipac/events/kahnfest to view the program and register for the conference and banquet dinner.
  • Jason Hogan joined the Physics Department as a new Assistant Professor. He has some excellent ideas relevant to probing gravity and for gravitational wave detection.
