How Extreme Energy Jets Escape a Black Hole

Researchers are using XSEDE supercomputers to better understand the forces at work at the center of the Milky Way galaxy. The work could reveal how instabilities develop in extreme energy releases from black holes. “While nothing – not even light – can escape a black hole’s interior, the jets somehow manage to draw their energy from the black hole.”

Video: Dark Matter – Detecting Gravity’s Hidden Hand

“One of today’s great challenges in physics is to observe individual dark matter particles coming in from the galaxy and striking particles on Earth. This talk presents the evidence for dark matter and introduces one of the most ambitious efforts to discover interactions of dark matter particles, using tons of cryogenic liquid in a deep underground laboratory.”

When Neutron Stars and Black Holes Collide

Working with an international team, scientists at Berkeley Lab have developed new computer models to explore what happens when a black hole joins with a neutron star – the superdense remnant of an exploded star. “If we can follow up LIGO detections with telescopes and catch a radioactive glow, we may finally witness the birthplace of the heaviest elements in the universe,” he said. “That would answer one of the longest-standing questions in astrophysics.”

Supercomputing the Dark Energy Survey at NCSA

Researchers are using NCSA supercomputers to explore the mysteries of Dark Matter. “NCSA recognized many years ago the key role that advanced computing and data management would have in astronomy and is thrilled with the results of this collaboration with campus and our partners at Fermilab and the National Optical Astronomy Observatory,” said NCSA Director, Bill Gropp.

Katrin Heitmann from the University of Chicago presented this talk at PASC17. “In this talk I will introduce HACC, the Hardware/Hybrid Accelerated Cosmology Code, which is being developed to combat the tremendous computational challenge to simulate our Universe.” After the talk, she discusses Dark Matter with Rich Brueckner from insideHPC.

PASC17 Plenary to Focus on Supercomputing Cosmology

Today the PASC17 Conference announced that this year’s plenary presentation will be entitled “Unlocking the Mysteries of the Universe with Supercomputers.” The plenary presentation will be given by Katrin Heitmann, Senior Member of the Computation Institute at the University of Chicago and the Kavli Institute for Physical Cosmology, USA.

Simulating the Earliest Generations of Galaxies with Enzo and Blue Waters

“Galaxies are complex—many physical processes operate simultaneously, and over a huge range of scales in space and time. As a result, accurately modeling the formation and evolution of galaxies over the lifetime of the universe presents tremendous technical challenges. In this talk I will describe some of the important unanswered questions regarding galaxy formation, discuss in general terms how we simulate the formation of galaxies on a computer, and present simulations (and accompanying published results) that the Enzo collaboration has recently done on the Blue Waters supercomputer. In particular, I will focus on the transition from metal-free to metal-enriched star formation in the universe, as well as the luminosity function of the earliest generations of galaxies and how we might observe it with the upcoming James Webb Space Telescope.”

New iBook brings us 72 Beautiful Galaxies

A new iBook by Dr. Stephen Perrenod looks at 72 Beautiful Galaxies. With a Foreword written by our own Rich Brueckner from insideHPC, the iPad “book” offers an interactive way to explore the universe. “In 72 Beautiful Galaxies we take you on a trip from relatively near to very far away in the universe, with images of 72 galaxies – and beyond that you will also see hundreds of galaxies as they are found in clusters.”

Faster Route to Insights with Hardware and Visualization Advances from Intel

An eye-popping visualization of two black holes colliding demonstrates 3D Adaptive Mesh Refinement volume rendering on next-generation Intel® Xeon Phi™ processors. “It simplifies things when you can run on a single processor and not have to offload the visualization work,” says Juha Jäykkä, system manager of the COSMOS supercomputer. Dr. Jäykkä holds a doctorate in theoretical physics and also serves as a scientific consultant to the system’s users. “Programming is easier. The Intel Xeon Phi processor architecture is the next step for getting more performance and more power efficiency, and it is refreshingly convenient to use.”

Supercomputing and the Search for Dark Matter

Over at CSCS, Simone Ulmer writes that Particle physicists using the Piz Daint supercomputer have determined what is known as the scalar quark content of the proton. The research will help efforts to detect and research dark matter.
