The search for planets beyond our solar system is about to gain some new recruits.Today, a team that includes MIT and is led by the Carnegie Institution for Science has released the largest collection...
Nearby massive star explosion 30 million years ago equaled detonation of 100 million suns
massive star explosion 30 million years ago detonation of 100 million suns
2016/5/6
A giant star that exploded 30 million years ago in a galaxy near Earth had a radius prior to going supernova that was 200 times larger than our sun, according to astrophysicists at Southern Methodist ...
Dark matter is called "dark" for a good reason. Although they outweigh particles of regular matter by more than a factor of 5, particles of dark matter are elusive. Their existence is inferred by thei...

Mysterious Starburst Unshrouded Nearby Galaxy
2015/11/12
NGC 253 is the nearest spiral galaxy with a nuclear starburst. The nuclear region is so veiled by large amounts of dust associated to the star formation process that it has been unclear, until now, wh...
Possible reduction of earthquake hazard on the Wellington Fault,New Zealand,after the nearby 1855,M 8.2 Wairarapa earthquake and implication for interpreting paleoearthquake intervals
Wellington region changes on Coulombfailure stress earthquake hazard
2015/9/16
Based on the indicative modelling, the changes in Coulomb failure function (?CFS) suggest that the W-HV segment and the T-P segment could be stable in at least the future 300 years and 190 years respe...
NOAO: Smashing Results About Our Nearby Galactic Neighbors
NOAO Smashing Results Nearby Galactic Neighbors
2015/1/8
The Magellanic Clouds are the two brightest nearby satellite galaxies to our own Milky Way galaxy. From a new study it appears that not only are they much bigger than astronomers calculated, but also ...
Title: Chandra Observations of the Galactic Center and Nearby Edge-on Galaxies
Galactic Center Nearby Edge-on Galaxies
2014/12/26
I review our recent Chandra surveys of the center region of the Milky Way and other nearby edge-on galaxies. Our Galactic center survey provides an unprecedented high-resolution, broad-band X-ray pano...
I highlight results from Chandr observations of nearby galaxies, including the Milky Way. These observations have offered insights into old mysteries and indications of new high energy astrophysical p...
Radio and Far-Infrared Emission as Tracers of Star Formation and Active Galactic Nuclei in Nearby Cluster Galaxies
AWM7 A426
2014/12/24
We have studied the radio and far-infrared (FIR) emission from 114 galaxies in the seven nearest clusters (<100 Mpc) with prominent X-ray emission to investigate the impact of the cluster environment ...
I review studies of the hot gaseous medium in and around nearby normal disk galaxies, including the Milky Way. This medium represents a reservoir of materials required for lasting star formation, a de...
Variations in 24-mu m morphologies among galaxies in the Spitzer Infrared Nearby Galaxies Survey: new insights into the Hubble sequence
ISM structure
2014/12/23
To study the distribution of star formation and dust emission within nearby galaxies, we measured five morphological parameters in the 3.6- and 24-μm wavebands for 65 galaxies in the Spitzer Infrared ...
Spectra of Nearby Galaxies Measured with a New Very Broadband Receiver
spectrographs spectroscopic
2014/12/23
Three-millimeter-wavelength spectra of a number of nearby galaxies have been obtained at the Five College Radio Astronomy Observatory (FCRAO) using a new, very broadband receiver. This instrument, whi...
The relations among 8, 24 and 160 mu m dust emission within nearby spiral galaxies
ISM galaxies
2014/12/23
We investigate the relations among the stellar continuum-subtracted 8 レm polycyclic aromatic hydrocarbon (PAH 8 レ m) emission, 24 レm hot dust emission and 160 レm cold dust emission in 15 nearby face-o...

ISM nuclei
2014/12/22
High-resolution mid-infrared spectra are presented for 155 nuclear and extranuclear regions from the Spitzer Infrared Nearby Galaxies Survey (SINGS). The fluxes for nine atomic forbidden and three mol...
Can nearby resonances enhance D-0-(D)over-bar(0) mixing?
Resonance mixing status the resonance parameters the resonance amplitude meson spectroscopy
2014/12/22
We study the contributions of resonances to mixing. Both and hybrid states are considered. Assuming reasonable values for the resonance parameters, we find relatively sizeable individual contributions...
