Romani Group: High energy Astrophysics
Current focus: Fermi/LAT study of Pulsars and Blazars: Astrophysical Populations and Accelerator Physics
LAT data – new discoveries piling up Supporting observations across the E-M spectrum, Modeling, Physics taking on rotators this year

Fermi Gamma-ray Space telescope
and the extreme particle accelerators
Fermi is studying lots of new sources – extreme particle accelerators
Broad-band picture needed - radio to optical, IR, UV, X-rays, …
Greg Madejski’s main area of interest: black holes and astrophysical jets
Future: Stanford is involved in development and planning for the next Caltech-led satellite mission NuSTAR, sensitive in the hard X-ray band – will be launched in 2012
Definitely looking for students / rotators! [email protected]; (650) 926-5184
Radio, optical, and X-ray image of a jet in the active galaxy Virgo-A
Fermi installed in the rocket fairing
Stefan Funk: the Crab Nebula flares and the Fermi Bubbles
• Fermi “Bubbles” • - diffuse, large-scale gamma-ray
emission in our Galaxy• No publication by the LAT team yet• Exact properties will yield important • information about their origin
Crab Nebula: mechanisms for particle acceleration? Extend energy spectrum to lower energies, understand time structure
Back to the Galaxy with Fermi
After Fermi: CTA – The Cherenkov Telescope array
• We plan to build a next-generation camera• Interested? Contact Stefan Funk, [email protected]
GS Orient 09-10
X-ray astrophysics Greg Madejski, Steve Allen, Roger Romani,
Roger Blandford, Stefan Funk, Hiro Tajima, Vahe’ Petrosian
X-ray data for celestial objects reveal extreme physics, but also allow us to use those objects to study cosmology
We use data from orbiting X-ray satellites: Chandra, XMM-Newton, Suzaku
Future: NuSTAR with Caltech in 2012, Astro-H with Japanese colleagues, 2015
Specific projects: how clusters of galaxies form and evolve?
How is energy released by matter falling into black holes?
NASA’s, European and Japanese facilities
Solar Flares Clusters of Galaxies
AGN
Roger Blandford - Fermi Topics
Mainly astrophysical theory: Gamma ray emission by relativistic
jets made by massive spinning black holes in galactic nuclei?
Comparing 3D relativistic MHD simulations with observations
Particle acceleration and magnetic amplification at supernova remnants
Making a self-consistent model of strong shock
Explaining flares in the Crab Nebula New approaches are needed to
explain rapid variation Classical radiation reaction
Astrophysical challenges are shedding new light on this old problem
Talk to Paul Simeon
Sarah Church’s Group Opportunities (1-2 rotators F, Sp)
Inflation???
• Development of radio amplifiers for investigating:
• Inflation through polarization of the Cosmic Microwave Background radiation (QUIET II, CHIP)
• Epoch of reionization through measurements of highly redshifted CO lines (large-format radio interferometer)
• Star formation history through molecular gas studies (Octopus at the Green Bank Telescope)
• Rotators participate in design tasks, prototype fabrication and testing
• In the longer term, thesis projects will include deployment, data taking and analysis
• Visit our lab – Varian 203/204 orstop by my office – Varian 344Note: I am away winter 2012
Sarah Church’s group ([email protected]): The Chajnantor Inflation Probe (CHIP)
CHIP Large format interferometer
for CMB measurements Prototyping underway with
deployment expected 2011 Possible rotation opportunities in
instrument development leading to deployed experiment
