Evidence for Correlated Titanium and Deuterium Depletion in the Galactic ISM
abundances abundances
2014/12/24
Current measurements indicate that the deuterium abundance in diffuse interstellar gas varies spatially by a factor of ~4 among sightlines extending beyond the Local Bubble. One plausible explanation ...
CO(1-0) in z gtrsim 4 Quasar Host Galaxies: No Evidence for Extended Molecular Gas Reservoirs
formation high-redshift
2014/12/24
We present 12CO(J = 1 → 0) observations of the high-redshift quasi-stellar objects (QSOs) BR 1202-0725 (z = 4.69), PSS J2322+1944 (z = 4.12), and APM 08279+5255 (z = 3.91) using the NRAO Green Bank Te...
Evidence for a population of high-redshift submillimeter galaxies from interferometric imaging
submillimeter formation
2014/12/23
We have used the Submillimeter Array to image a flux-limited sample of seven submillimeter galaxies, selected by the AzTEC camera on the JCMT at 1.1 mm, in the COSMOS field at 890 μ m with ~2'' resolu...
Self-regulated fueling of galaxy centers: Evidence for star formation feedback
kinematics dynamics galaxies:
2014/12/23
Using new, high-resolution interferometric observations of the CO and HCN molecules, we directly compare the molecular and ionized components of the interstellar medium in the center of the nearby spi...
The physical scale of the far-infrared emission in the most luminous submillimetre galaxies – II. Evidence for merger-driven star formation
interferometers interactions
2014/12/22
We present high-resolution 345-GHz interferometric observations of two extremely luminous (Lir≳ 1013 L⊙), submillimetre-selected galaxies (SMGs) in the Cosmic Evolution Survey (COSMOS) field wit...
ALMA finds best evidence yet for galactic merger in distant protocluster（图）
ALMA galactic merger distant protocluster
2014/12/1
Nestled among a triplet of young galaxies more than 12.5 billion light-years away is a cosmic powerhouse: a galaxy that is producing stars nearly 1,000 times faster than our own Milky Way. This energe...
An Anomaly in the Angular Distribution of Quasar Magnitudes: Evidence for a Bubble Universe with a Mass ~10^21 M\odot
Anomaly Angular Distribution Quasar Magnitudes Bubble Universe Mass
2012/2/21
Quasars provide our farthest-reaching view of the Universe. The Sloan Survey now contains over 100,000 quasar candidates. A careful look at the angular distribution of quasar magnitudes shows a surpri...
U Sco 2010 outburst: observational evidence of an underlying ONeMg white dwarf
stars: individual: USco –novae, cataclysmic variables
2011/10/12
This paper presents U Sco nebular spectra collected in the period March-May 2010 after the binary outburst on Jan 28, 2010. The spectra display strong [Ne V] and [Ne III] lines that can be used to com...
Spectra of globular clusters in the Sombrero galaxy: evidence for spectroscopic metallicity bimodality
globular clusters: general galaxies: individual: Sombrero (M104: NGC4594) galaxies: star clusters
2011/9/28
We present a large sample of over 200 integrated-light spectra of confirmed globular clusters (GCs) associated with the Sombrero (M104) galaxy taken with the DEIMOS instrument on the Keck telescope. A...
New evidence that matter and antimatter may behave differently（图）
matter antimatter elementary particles nuclear reactions
2010/9/21
Neutrinos, elementary particles generated by nuclear reactions in the sun, suffer from an identity crisis as they cross the universe, morphing between three different “flavors.” Their antimatter count...

QSO Pairs across Active Galaxies: Evidence of Blueshifts?
Quasars emission lines—quasars absorption lines—cosmology miscellaneous
2010/9/16
Several QSO pairs have been reported and their redshifts determined, where the two objects in each pair are located across an active galaxy. The usually accepted explanation of such occurrences is tha...
