Postdoctoral position in numerical relativity at UIUC
by Witek, Helvi 16 Sep '19

16 Sep '19

Dear all, the Illinois Relativity Group (consisting of Professors Stuart Shapiro, Nico Yunes and, as of next January, myself as well as postdocs and PhD students) is opening a postdoctoral research position in numerical relativity and relativistic astrophysics. You can find more details below and here: https://hyperspace.uni-frankfurt.de/2019/09/04/postdoctoral-research-positi… We would appreciate it if you could circulate the information to interested candidates. Best wishes, Helvi ==== Postdoctoral Research Position in Numerical Relativity and Computational Astrophysics University of Illinois at Urbana-Champaign Applications are invited for a postdoctoral research position in the Illinois Relativity Group. The candidate should have expertise in numerical relativity and relativistic astrophysics. Some experience in computational hydrodynamics and/or computational MHD would be desirable. Applicants should go online at https://my.physics.illinois.edu/join/ to submit their application, which must include a cover letter, curriculum vitae, list of publications, brief description of research interests, and the names, mailing and email addresses of three references. Please contact Elisabeth Greifenkamp at greifenk(a)illinois.edu<mailto:greifenk@illinois.edu> if you have any questions. Applications should be posted by DEC 1, 2019 for full consideration. The starting date of the position is AUG 15, 2020. The successful applicant will join Professor Stuart Shapiro in developing and applying the tools of numerical relativity together with computational hydrodynamics, MHD, and/or stellar dynamics to tackle diverse problems in general relativity and astrophysics. Recent topics include the inspiral and coalescence of compact binaries, the generation of gravitational waves, magnetized neutron stars, magnetorotational stellar collapse, accretion onto isolated and binary black holes, the formation and cosmological growth of supermassive black holes in the early universe, and the dynamics of dark matter halos and spikes around black holes. Some of this work is geared to identifying astrophysically plausible, strong-field sources of gravitational waves and calculating gravitational waveforms detectable by LIGO/VIRGO, KAGRA, LISA and the PTA. For these “multimessenger” sources we are also exploring counterpart electromagnetic signals, including gamma-ray bursts and kilonovae, as well as neutrinos. In addition to Professor Shapiro, the Illinois Relativity Group includes Professors Nicolas Yunes and Helvi Witek, their postdocs, PhD and undergraduate research students. It maintains close interactions with UIUC colleagues in Physics, Astronomy and NCSA, in addition to several outside collaborators. The University of Illinois is an Affirmative Action/Equal Opportunity employer. -- =========================================== Dr. Helvi Witek Royal Society University Research Fellow Theoretical Particle Physics and Cosmology.

Error running nsns_test.par with file resu.d
by Atul Kedia 15 Sep '19

Hello, I am trying to do a test run with nsns_test.par from the default ETK package from directory /Cactus/repos/wvuthorns_diagnostics/NSNS_parameter_files/ and getting the following error: ERROR from host epycfe.crc.nd.edu process 1 while executing schedule bin HydroBase_Initial, routine Meudon_Bin_NS::Meudon_Bin_NS_initialise in thorn Meudon_Bin_NS, file /afs/ crc.nd.edu/user/i/isuh/astroph/Cactus/08132019/Cactus/configs/sim/build/Meu… : -> File "resu.d" does not exist.

I obtained the file "resu.d" from http://astro.phys.wvu.edu/zetienne/resu.d but don't know where I should put the file. I think this is a Lorene data file (based on http://dspace-unipr.cineca.it/bitstream/1889/3328/1/Thesis_Maione.pdf). Does anyone know where to place it? Thank you, Atul Kedia, Physics Graduate student University of Notre Dame

CarpetIOHDF5 recover failure with manual topology
by Yosef Zlochower 15 Sep '19

15 Sep '19

Hi, I have been trying to debug why some runs I was performing could not recover from a checkpoint file, but would otherwise proceed as normal. I attached a minimalist parfile showing the problem. A small grid is manually distributed over 8 processors and terminates at iteration 2. An attempt at recover fails with nans on grid::x. If the manual topology section is commented out, no problems are seen. -- Dr. Yosef Zlochower Center for Computational Relativity and Gravitation Associate Professor School of Mathematical Sciences Rochester Institute of Technology 85 Lomb Memorial Drive Rochester, NY 14623 Office:74-2067 Phone: +1 585-475-6103 yosef(a)astro.rit.edu CONFIDENTIALITY NOTE: The information transmitted, including attachments, is intended only for the person(s) or entity to which it is addressed and may contain confidential and/or privileged material.

symmetries and IllinoisGRMHD
by Haas, Roland 13 Sep '19

13 Sep '19

Hello all, since this came up at the ET meeting in London: can someone please remind me what the support for (Cactus) symmetries in IllinoisGRMHD is? My recollection is that, due to the way that the staggered field work, that none of the ReflectionSymmetry, RotatingSymmetry90, RotatingSymmetry180 thorns could be used with the staggered vector (and scalar) potentials. Is this correct? Yours, Roland -- My email is as private as my paper mail. I therefore support encrypting and signing email messages. Get my PGP key from http://pgp.mit.edu .

user map code
by Haas, Roland 11 Sep '19

11 Sep '19

Hello Niels, after the discussion at the ET meeting in London last week, would you mind sharing the scripts (or instructions if you have any) that were used to produce the user map at: https://bhptoolkit.org/users.html For the ET we would like to have a similar life map: https://trac.einsteintoolkit.org/ticket/260 It seems that Google's API can find out the location based on the names (at least based on the original simple MMA script that was used at NCSA).

Simulation tools' problem in loading binary data
by Hassan Khalvati 09 Sep '19

09 Sep '19

Hello, I am using simulation tools in Mathematica to extract and visualize my simulation results and thanks to Ian, and Barry, it is really helpful. but I have just faced a problem in checking the binary separation. that is when I am asking to ReadBinarySeparation from my simulations, it is posting an error: "Plus cannot operate on DataTables with different coordinates. To allow this, use the WithResampling function." and I have tested for 3 different simulation results and all have the same error message. But if I am replacing the "BH_diagnostics.ah1.gp" file from the simulation tools' TestSimulation, I am getting output, however that output does not actually belong to my data, the point is that there is no error in this case. And when I am using "WithResampling" function, I think some of my data is missing, because my data table is reducing to 990, from about 27000. I have attached the diagnostics files from both, my results, and "Testsimulation", in case it is needed. I would be grateful if anyone could help me with this. With regards, Hassan -- Hassan Khalvati Sharif University of Tehran
