Astronomers have found an enormous, glowing blob of gas in the distant universe, with no obvious source of power for the light it is emitting. Called an "enormous Lyman-alpha nebula" (ELAN), it is the...
We have examined Chandra observations of the recently discovered X-ray thread G0.13-0.11 in the Galactic center Radio Arc region. Part of the Chandra data was studied by Yusef-Zadeh, Law, & Wardle, wh...
Chandra Observation of Supernova Remnant G54.1+0.3: A Close Cousin of the Crab Nebula
G54.1+0.3 jets and outfl ows
2014/12/26
We present a Chandra Advanced CCD Imaging Spectrometer observation of supernova remnant G54.1+0.3. This supernova remnant is resolved into several distinct X-ray-emitting components: a central bright ...
The Chandra View of DA 530: A Subenergetic Supernova Remnant with a Pulsar Wind Nebula?
DA 530 (G93.3+6.9) ISM
2014/12/23
DA 530 (G93.3+6.9) is a high Galactic latitude supernova (SN) remnant with a well-defined shell-like radio morphology and an exceptionally low X-ray-to-radio luminosity ratio. Based on a Chandra ACIS ...
DISTANCE DETERMINATION TO THE CRAB-LIKE PULSAR WIND NEBULA G54.1+0.3 AND THE SEARCH FOR ITS SUPERNOVA REMNANT SHELL

2014/12/23
We discovered a large-scale shell G53.9+0.2 around the Crab-like pulsar wind nebula (PWN) G54.1+0.3 with 1420 MHz continuum Very Large Array observations. This is confirmed by a new infrared (IR) imag...
DISCOVERY OF A LUMINOUS BLUE VARIABLE WITH AN EJECTION NEBULA NEAR THE QUINTUPLET CLUSTER
variable star Pistol Star
2014/12/22
We report on the discovery of a luminous blue variable (LBV) lying 7 pc in projection from the Quintuplet cluster. This source, which we call LBV G0.120 – 0.048, was selected for spectroscopy owing to...
THE RADIO PROPERTIES AND MAGNETIC FIELD CONFIGURATION IN THE CRAB-LIKE PULSAR WIND NEBULA G54.1+0.3
filamentary loop-like structures
2014/12/22
We present a multifrequency radio investigation of the Crab-like pulsar wind nebula (PWN) G54.1+0.3 using the Very Large Array. The high resolution of the observations reveals that G54.1+0.3 has a com...
We have observed the radio nebula surrounding the Galactic LBV candidate G79.29+0.46 with the EVLA at 6 cm. These new radio observations allow a morphological comparison between the radio emission, wh...
