A high-frequency survey of the southern Galactic plane for pulsars
Results of an HF survey designed to detect young, distant, and short-period pulsars are presented. The survey detected a total of 100 pulsars, 46 of which were previously unknown. The periods of theExpand
Large convection cells as the source of Betelgeuse's extended atmosphere
Supergiant stars such as Betelgeuse have very extended atmospheres, the properties of which are poorly understood. Alfvén waves, acoustic waves,, and radial pulsations have all been suggested asExpand
A Spatially Resolved, Semiempirical Model for the Extended Atmosphere of α Orionis (M2 Iab)
We have constructed a detailed mean density and temperature model for the extended outer atmosphere of the O-rich supergiant Betelgeuse (??Ori [M2 Iab]), which extends from 1.0 to 10.0 stellar radii.Expand
A Geometrically Supported z ~ 10 Candidate Multiply Imaged by the Hubble Frontier Fields Cluster A2744
The deflection angles of lensed sources increase with their distance behind a given lens. We utilize this geometric effect to corroborate the z_phot ≃ 9.8 photometric redshift estimate of a faintExpand
THE TAIWAN ECDFS NEAR-INFRARED SURVEY: ULTRA-DEEP J AND KS IMAGING IN THE EXTENDED CHANDRA DEEP FIELD-SOUTH
We present ultra-deep J and K{sub S} imaging observations covering a 30' Multiplication-Sign 30' area of the Extended Chandra Deep Field-South (ECDFS) carried out by our Taiwan ECDFS Near-InfraredExpand
TANGO I: ISM in nearby radio galaxies. Molecular gas
Powerful radio-AGN are hosted by massive elliptical galaxies which are usually very poor in molecular gas. Nevertheless gas is needed in the very center to feed the nuclear activity. We aim to studyExpand
A RIGOROUS FREE-FORM LENS MODEL OF A2744 TO MEET THE HUBBLE FRONTIER FIELDS CHALLENGE
Hubble Frontier Fields (HFF) imaging of the most powerful lensing clusters provides access to the most magnified distant galaxies. The challenge is to construct lens models capable of describingExpand
Radially inflowing molecular gas in NGC 1275 deposited by an x-ray cooling flow in the perseus cluster
We have imaged in CO(2-1) the molecular gas in NGC 1275 (Perseus A), the cD galaxy at the center of the Perseus Cluster, at a spatial resolution of similar to 1 kpc over a central region of radiusExpand
Radio constraints on coronal models for dMe stars
Radio data are used to test coronal models for dMe stars. Specifically, we show that photospheric magnetic field observations imply that the low corona of a dMe star should be saturated by magneticExpand
