Powerful New Telescope Astronomers Observing One of the Oldest Objects the Universe
2017/11/23
Astronomers using the Large Millimeter Telescope (LMT), which is operated jointly by the University of Massachusetts Amherst and Mexico’s Instituto Nacional de Astrofísica, óptica y Electrónica, repor...
When certain massive stars use up all of their fuel and collapse onto their cores, explosions 10 to 100 times brighter than the average supernova occur. Exactly how this happens is not well understood...
Powerful High-Velocity Dispersion Molecular Hydrogen Associated with an Intergalactic Shock Wave in Stephan's Quintet
interactions intergalactic medium
2014/12/23
We present the discovery of strong mid-infrared emission lines of molecular hydrogen of apparently high-velocity dispersion (~870 km s-1) originating from a group-wide shock wave in Stephan's Quintet....
Powerful H$_2$ Line-cooling in Stephan's Quintet : I - Mapping the Significant Cooling Pathways in Group-wide Shocks,
intergalactic medium shock waves
2014/12/22
We present results from the mid-infrared spectral mapping of Stephan's Quintet using the Spitzer Space Telescope. A 1000 km/s collision has produced a group-wide shock and for the first time the large...
A Hotspot for Powerful Cosmic Rays PHYSICISTS A STEP CLOSER TO FINDING MYSTERIOUS SOURCES
The universe Ray Hot spots. Mysterious The big dipper. High-energy cosmic rays The sun
2014/7/18
July 8, 2014 – An observatory run by the University of Utah found a “hotspot” beneath the Big Dipper emitting a disproportionate number of the highest-energy cosmic rays. The discovery moves physics a...
Powerful relativistic jets in spiral galaxies

2011/10/9
The discovery of high-energy (E>100 MeV) gamma rays from Narrow-Line Seyfert 1 Galaxies (gamma-NLS1s) has confirmed the presence of powerful relativistic jets in this class of active galactic nuclei (...
Disk, merger, or outflow ? Molecular gas kinematics in two powerful obscured QSOs at z>3.4
Galaxies: high-redshift – Submillimeter: ISM – Submillimeter: galaxies – (Galaxies:) quasars: individual
2011/10/8
We report on the detection of bright CO(4-3) line emission in two powerful, obscured quasars discovered in the SWIRE survey, SW022513 and SW022550 at z>3.4. We analyze the line strength and profile to...
The rapid rotation (P=0.44 d) of the M dwarf V374Peg (M4) along with its intense magnetic field point toward magneto-centrifugal acceleration of a coronal wind. In this work, we investigate the struct...
Evidence for a maximum jet efficiency for the most powerful radio galaxies

2010/12/24
We use new mid-infrared (mid-IR) photometry from the Spitzer Space Telescope to study the relations between low-frequency radio luminosity density L_151MHz, mid-IR (12um rest-frame) luminosity L_12um,...
