The author list: Christian Ott, Ernazar Abdikamalov, Philipp Mösta, Roland Haas, Steve Drasco, Evan O'Connor, Christian Reisswig, Casey Meakin, and Erik Schnetter.
(Important aside: You have probably noticed that there is not a single woman on the author list. The extreme underrepresentation of women in theoretical and computational astrophysics is a big problem that is hurting our field.)
My main contributions were: Defining the scope of the project, doing the actual simulations (which were carried out on supercomputers at NERSC, NICS, and TACC), overseeing the analysis and visualization, and writing the paper.
|Ernazar Abdikamalov, TAPIR, Caltech|
Some background on Ernazar: I first met Ernazar (who originally comes from Uzbekistan) when he was a PhD student working with Luciano Rezzolla at SISSA at Trieste. I ended up collaborating with Ernazar on the final paper (on general-relativistic simulations of accretion induced collapse) towards his PhD thesis in 2009. He then went to work as a postdoc with my friends in the numerical relativity group at LSU's Center for Computation and Technology. Knowing the outstanding work he does, I brought him to Caltech first as a long-term visitor, then hired him as a postdoc, once I had the money to do so. His current primary research interest and specialty is radiation transport and we have a few papers together on this and other subjects.
|Philipp Mösta, TAPIR, Caltech|
Some background on Philipp: Philipp is a recent PhD (early 2012) coming out of Luciano Rezzolla's group at the Albert Einstein Institute (the Max Planck Institute for Gravitational Physics in Potsdam, Germany). I have known him since 2006, when he was at the AEI working on a numerical relativity code for his master's thesis. His PhD research was on electromagnetic fields and their interaction with merging binary black hole systems. He arrived at Caltech in November 2011 and is a postdoc in my group. His main interest right now are magnetohydrodynamic processes in core-collapse supernovae, but he continues to work on more fundamental numerical relativity problems and also helps with double neutron star merger simulations using the SpEC code of the Simulating eXtreme Spacetimes collaboration.
|Roland Haas, TAPIR, Caltech|
Some background on Roland: Roland received his PhD from the University of Guelph, where he worked with Eric Poisson on self-force calculations in general relativity. He then worked in Pablo Laguna's group at Georgia Tech, where he became involved in the Einstein Toolkit. In 2010, he won a Canadian NSERC postdoctoral fellowship, which he took to Caltech in the fall of 2011. His main current research is focused on the double neutron star merger problem, which he is tackling with the SpEC code. He has also been working closely with Christian Reisswig on the new multi-block extension to Zelmani.
|Steve Drasco, Grinnell College|
Some background on Steve: Steve is a relativist by training and received his PhD from Cornell, working with Eanna Flanagan. His main research focus has been on extreme and intermediate mass ratio binary black hole inspirals. He came to Caltech/JPL as a postdoc in 2005, moved to the Albert Einstein Institute in 2008, was a lecturer at CalPoly San Luis Obsipo from 2010 until this June. He is now an Assistant Professor of Physics at Grinell College and has a visitor appointment in my group in TAPIR. Steve has always had a great talent for visualizing his work. Some of his stuff has recently been featured in Physics Today. Also check out his cool movies of these inspirals. Steve loves fast cars and owns two Porsches.
|Dr. Evan O'Connor (right) and Christian Ott (left).|
Some background on Evan: Evan is the first PhD that I produced and I am as proud as a "parent" could possibly be! The picture on the right shows Evan and me on the patio of Caltech's Cahill Center for Astronomy & Astrophysics right after his defense. The hat that we made for him says "Licensed Supernova Theorist". Evan graduated this June and, since September 1, he is a postdoctoral fellow at the Canadian Institute for Theoretical Astrophysics at the University of Toronto. His main current interests are neutrino transport, neutrino microphysics, and the nuclear equation of state. Check out his publication list. It's already quite impressive!
|Christian Reisswig, TAPIR, Caltech|
Some background on Christian: I have known Christian since ~2005, when he arrived as a master's student at the Albert Einstein Institute (where I was a PhD student at the time). Already back then, he played around with an early multi-block infrastructure. In his PhD research (which he concluded in 2010), he worked on binary black hole inspiral and merger simulations and became one of the leading experts in extracting gravitational waves from such simulations. He arrived as my first postdoc at Caltech in early 2010 and was awarded an Einstein Fellowship in 2012. His main research interests right now are black hole formation, his magical next-generation Simsalabim high-performance computing infrastructure (ask him about it after he has had a few drinks!), and rapidly rotating core collapse.
|Casey Meakin, LANL|
Some background on Casey: I have known Casey since 2001 and he is one of my few close long-time friends. We were both graduate students at Steward Observatory at the University of Arizona (well, I was sort of an "exchange student") at that time working with Adam Burrows. Casey subsequently worked with Dave Arnett on multi-dimensional stellar evolution and graduated in 2006. He was a postdoc at the Flash Center at the University of Chicago, then went back to Arizona for a while and is now a Scientist in the Theoretical Division of Los Alamos National Laboratory and adjunct faculty at Steward Observatory.
|Erik Schnetter, Perimeter Institute|
Some background on Erik: I have known Erik since 2003 and he is another very close, long-time friend. I met him when he was a postdoc at the Albert Einstein Institute and I was a graduate student there. Erik (together with Ian Hawke) basically trained me in numerical relativity and computational science. In 2005, he moved as a Research Assistant Professor and Staff Scientist to the Center for Computation and Technology at LSU and in 2010 he became Research Technologies Group lead at the Perimeter Institute in Waterloo, Ontario, Canada. He is also adjunct faculty at the University of Guelph.
