Supernova SN2013cu Picked on a Routine Sky Scan by the iPTF

Supernovae—stellar explosions—are incredibly energetic, dynamic events. It is easy to imagine that they are uncommon, but the universe is a big place and supernovae are actually fairly routine.

Astronomers Believe Smith Cloud is Wrapped in Halo of Dark Matter

Like a bullet wrapped in a full metal jacket, a high-velocity hydrogen cloud hurtling toward the Milky Way appears to be encased in a shell of dark matter, according to a new analysis of data from the National Science Foundation's Robert C. Byrd Green Bank Telescope (GBT). Astronomers believe that without this protective shell, the high-velocity cloud (HVC) known as the Smith Cloud would have disintegrated long ago when it first collided with the disk of our Galaxy.

Frontiers of Cold Matter on May 29-30 Celebrating Paul Julienne’s 70th Birthday

JQI fellow Paul Julienne has recently retired from NIST but continues to perform high-level theoretical research in the subject he helped to create---ultracold matter. In honor of his birthday, a meeting called Frontiers of Cold Matter is being held May 29-30 at JQI.

The P5's Report Recommends Strategic Path for US Particle Physics

Particle physics will become even more of an international endeavor in the coming decades, according to a panel charged with developing a strategic plan for the future of US particle physics, whose long-awaited recommendations were released today.

Researchers Study the Demagnetization Dynamics of a Three-Dimensional Fermi Gas

Fermi gases in the so-called unitary regime—where the diverging interactions between atoms make their thermodynamics universal—are an excellent test bed for an array of strongly interacting matter systems. Two places to find a unitary Fermi gas are in the crust of a neutron start, and in basement of McLennan.

Researchers Test Universality of Free Fall by Measuring Acceleration of Two Different Atomic Species

Two major theories exist in modern physics: general relativity, the principle which governs our current understanding of gravity, and quantum mechanics, which explains the nature of extremely tiny objects such as electrons.

Dark, Dense and Dusty Cosmic Clumps Throw Deepest Shadows

Astronomers have found cosmic clumps so dark, dense and dusty that they throw the deepest shadows ever recorded. Infrared observations from NASA's Spitzer Space Telescope of these blackest-of-black regions paradoxically light the way to understanding how the brightest stars form.

First Direct Confirmation of Wolf-Rayet Star’s Death in a Type IIb Supernova

Our Sun may seem pretty impressive: 330,000 times as massive as Earth, it accounts for 99.86 percent of the Solar System's total mass; it generates about 400 trillion trillion watts of power per second; and it has a surface temperature of about 10,000 degrees Celsius. Yet for a star, it's a lightweight.

Wolf-Rayet Star may be Likely Progenitor of Recently Exploded Supernova

Wolf-Rayet stars are very large and very hot. Astronomers have long wondered whether Wolf-Rayet stars are the progenitors of certain types of supernovae. New work from the Palomar Transient Factory team, including Carnegie’s Mansi Kasliwal, is homing in on the answer. They have identified a Wolf-Rayet star as the likely progenitor of a recently exploded supernova. This work is published by Nature.

New WISE Results do not Corroborate Black Hole 'Doughnut' Theory

A survey of more than 170,000 supermassive black holes, using NASA's Wide-field Infrared Survey Explorer (WISE), has astronomers reexamining a decades-old theory about the varying appearances of these interstellar objects.
