Disclaimer: We strive for accurate information but do not always get it all perfect. Please send us any corrections and additions that you would like us to include in the online version of the newsletter.

  • How to invite a visitor or speaker to KIPAC?

    • We now have a KIPAC visitor form that we encourage you to use for anyone you expect to visit KIPAC -- future speakers (for tea, cosmology seminar, colloquium), short-term visitors, etc. This public form can also be used by those who would like to visit or give a presentation at KIPAC. Please encourage your colleagues to use the KIPAC visitor form when they contact you about possible visits.  That will be very helpful for our planning purposes.  

  • KIPAC teabot update

    • KIPAC TeaBot is an automatic system that browses through new arXiv astro-ph papers everyday and sends personal suggestions to subscribers. It also sends discussion suggestions to Tea organizers, and discovers new papers that are authored by KIPAC members. You can now subscribe and customize your KIPAC teabot email subscription and it will bring papers to your attention that are likely to interest you and also sort all of astro-ph using the same machine intelligence.

  • KIPAC Committee updates:

    • The KIPAC Astrophysics Colloquium committee members are William East, Yashar Hezaveh, Irina Zhuravleva, and Jonathan Zrake.  Please feel free to use our KIPAC visitor form for suggestions for KIPAC Colloquium speakers.

    • Roger Blandford will be leading the KIPAC postdoctoral search this year. The full  committee includes Roger Blandford, Peter Graham, Tom Shutt, Risa Wechsler, Bruce Macintosh, and Chao-Lin Kuo. If you know any outstanding postdoc candidates - please do encourage them to apply.

  • Selected news from KIPAC over the last few months --

    • News from LSST:  

      • Congratulations to the LSST Camera team for successfully passing the CD-3 review in August, which allows start of construction!

      • The LSST Project and Community Workshop 2015 was held in Bremerton WA in August. In addition to project and science meetings, the meeting included an Observing Strategy Workshop, and six public lectures plus an astronomy slam featuring five different astronomers at each of five venues in Bremerton -- a small city that truly welcomed the LSST meeting with open arms! See this Puget Sound blog for a conversation with LSST Director Steve Kahn and Bob Abel -- the mastermind behind the public outreach -- pictured in the photo.

    • The DESI Project has just achieved CD2 Approval. CD2 approval authorizes the project scientific scope, schedule, and funding profile from the Department of Energy.  DESI is currently on track to start observations in 2019, and will be observing redshifts for more than 30 million galaxies and quasars to map the evolution of the Universe’s expansion rate and growth of structure.  Risa Wechsler serves as the Co-Spokesperson of the Science Collaboration, Aaron Roodman and Kevin Reil are leading the focus and alignment activities, and Eli Rykoff is currently engaged in validation of the precursor imaging surveys.

    • Aaron Roodman is part of an eight-person strong Cosmic Visions panel on dark energy. The group will collect and coordinate ideas from the HEP community for research activities, experiments, projects or facilities that will complement, build on, and extend beyond the current program planned for the 2020s in the 2014 P5 report (DESI, LSST, CMB-S4) in investigating the physics probed by surveys. The group was charged to produce a white paper in January 2016 that will include diverse ideas for the future relevant to the HEP program, ranging from blue sky methods to new project concepts to further use of existing facilities. There will be a small workshop here in the middle of November to allow for input and wide ranging discussion to inform the panel.

    • Bruce Macintosh is a member of the “Mid-decadal Astro Survey”.  Watch for local discussions, and please discuss with Bruce your ideas.

    • DES discovered eight new dwarf galaxy candidates, bringing the total number of DES candidates for 2015 to 17!  This work was led by former KIPAC students Alex Drlica-Wagner and Keith Bechtol, with involvement from Eli Rykoff, Risa Wechsler, Yao-Yuan Mao, and others at KIPAC. These new detections will be  again very exciting for our Fermi team to follow up on.

    • DES had a number of science papers out this summer mostly based on the Science Verification data, including the first cosmology results with weak lensing, which involved many years of work from many KIPAC people including Matt Becker, who led the shear two-point measurements, and Eli Rykoff, who played a key role in much of the early data analysis.  DES started the third of five years of observations last month.

    • The joint Japanese-US X-ray - sensitive satellite Astro-H is on-track for launch in early 2016.  A number of KIPAC members -- Greg Madejski, Steve Allen, Roger Blandford, Ashley King, Norbert Werner, and Irina Zhuravleva -- are actively involved in preparing the observing plan for the mission.  The prime instrument aboard Astro-H will be a high-resolution (1/1000 at 6 keV) calorimetric X-ray spectrometer.  

    • The Fermi Large Area Telescope collaboration had its Fall meeting in Torino during the week of August 31st.  The Collaboration members discussed the recent results, and worked on plans for the presentations at the Fermi Symposium, to take place in Washington, November 9-13 2015.  

    • Bruce Macintosh, the lead investigator for the Gemini Planet Imager, and his team have discovered a 'young Jupiter' exoplanet; the discovery was published in Science.

    • KIPAC research on the early Universe is featured in the hour-long BBC2 program Cosmic Dawn, episode 14 in season 54 of the well-known series Horizon. The full show can be streamed.

  • Computing and astro/cosmology classes -- of special interest to first-year grad students:

    • A group of computer savvy KIPAC members led by Yao-Yuan Mao is organizing a “KIPAC Computing Bootcamp” -- an event aimed at introducing the computing tools and facilities used in many KIPAC projects. The bootcamp will take place during the first week of the quarter, with a schedule that accommodates graduate courses: Wed 9/23 from 1:30 to 3:00 and Thurs 9/24 from 1:00 to 2:30 on campus (basic shell scripts and Python), and Fri 9/25 from 12:30 to 5:00 at SLAC (more advanced topics in Python, KIPAC computing resources, Git, SQL).  See the bootcamp webpage for details and registration.  

    • All grad students working in astrophysics and cosmology -- including first-year students -- are encouraged to consider enrolling in a new five-week, two-unit course, PHYSICS 366 - Special Topics in Astrophysics: Statistical Methods. The prerequisite is basic familiarity with Python coding (or willingness to learn quickly!) and basic statistics, and an interest in astrophysics and cosmology. The course will primarily be targeted at first and second year students, but we welcome participation from more experienced students.  See the course website for more information.

  • Three LSST @ SLAC presentations are scheduled for the Autumn quarter; they will be held at 11:30 in the Fred Kavli Building 3rd-floor conference room:
