Research done at Cornell has uncovered from gravitation wave data the first potential signs of spin-orbit resonances in binary black holes, a step toward understanding the mechanisms of supernovas and...
Chandra Observation of the Edge-on Galaxy NGC 3556 (M108): Violent Galactic Disk-Halo Interaction Revealed
NGC 3556 spiral
2014/12/26
We present a 60 ks Chandra ACIS-S observation of the isolated edge-on spiral galaxy NGC 3556, together with a multiwavelength analysis of various discrete X-ray sources and diffuse X-ray features. Amo...
Large-scale structure of the molecular gas in Taurus revealed by high linear dynamic range spectral line mapping
molecules structure
2014/12/23
We report the results of a 100 deg2 survey of the Taurus molecular cloud region in 12CO and 13CO J = 1→ 0. The image of the cloud in each velocity channel includes 3 × 106 Nyquist-sampled pixels on a ...
Birth of planets revealed in astonishing detail in ALMA's 'best image ever'
best image ever planet
2014/11/10
Astronomers have captured the best image ever of planet formation around an infant star as part of the testing and verification process for the Atacama Large Millimeter/submillimeter Array’s (ALMA) ne...

2014/12/1
Astronomers have captured the best image ever of planet formation around an infant star as part of the testing and verification process for the Atacama Large Millimeter/submillimeter Array’s (ALMA) ne...
Strange events have long been linked to nights of a full moon, though careful scrutiny dispels any association. So, when signals bounced off the lunar surface returned surprisingly faint echoes on ful...
The remnant of SN1987A revealed at (sub-)mm wavelengths
circumstellar matter – supernovae: individual: SN1987A – ISM: ISM
2011/9/29
Context: Supernova 1987A (SN1987A) exploded in the Large Magellanic Cloud (LMC). Its proximity and rapid evolution makes it a unique case study of the early phases in the development of a supernova re...
The Mass Distribution of the Great Attractor as Revealed by a Deep NIR Survey
Distribution Great Attractor Revealed Deep Survey
2011/9/28
This paper presents the analysis of a deep near-infrared J,H,Ks-imaging survey (37.5 sq deg) aimed at tracing the galaxy distribution of the Great Attractor (GA) in the Zone of Avoidance along the so-...
The spiral structure of the Galaxy revealed by CS sources and evidence for the 4:1 resonance
Galaxy Astrophysics (astro-ph.GA)
2010/12/28
We present a map of the spiral structure of the Galaxy, as traced by molecular CS emission associated with IRAS sources which are believed to be compact HII regions. The CS line velocities are used to...
Cosmic star formation history revealed by the AKARI, & Spatially-resolved spectroscopy of an E+A (Post-starburst) system
evolution galaxies:starburst
2010/3/8
We reveal cosmic star-formation history obscured by dust using deep infrared observation with the AKARI. A continuous filter coverage in the mid-IR wavelength (2.4, 3.2, 4.1, 7, 9, 11, 15, 18, and 24u...
