A 1D fluid model of the Centaurus A jet
(2018-09-27)We implement a steady, one-dimensional flow model for the X-ray jet of Centaurus A in which entrainment of stellar mass loss is the primary cause of dissipation. Using over 260 ks of new and archival Chandra/ACIS data, we ... -
2 mm GISMO Observations of the Galactic Center. I. Dust Emission
(The American Astronomical Society, 2019-11-01)The Central Molecular Zone (CMZ), covering the inner ∼ 1 ◦ of the Galactic plane has been mapped at 2 mm using the GISMO bolometric camera on the 30 m IRAM telescope. The 2100 resolution maps show abundant emission from ... -
2 mm GISMO Observations of the Galactic Center. II. A Nonthermal Filament in the Radio Arc and Compact Sources
(The American Astronomical Society, 2019-11-01)We have used the Goddard IRAM 2-Millimeter Observer (GISMO) with the 30 m IRAM telescope to carry out a 2 mm survey of the Galaxy’s central molecular zone (CMZ). These observations detect thermal emission from cold ISM ... -
The 2001 Superoutburst of WZ Sagittae
(IOP, 2002-06-10)We report the results of a worldwide campaign to observe WZ Sagittae during its 2001 superoutburst. After a 23 yr slumber at V = 15.5, the star rose within 2 days to a peak brightness of 8.2, and showed a main eruption ... -
2FHL: THE SECOND CATALOG OF HARD FERMI-LAT SOURCES
(IOP, 2016-01-14)We present a catalog of sources detected above 50 GeV by the Fermi-Large Area Telescope (LAT) in 80 months of data. The newly delivered Pass 8 event-level analysis allows the detection and characterization of sources in ... -

3D Path-Following using MRAC on a Millimeter-Scale Spiral-Type Magnetic Robot
(IEEE, 2020-01-24)This paper focuses on the 3D path-following of a spiral-type helical magnetic swimmer in a water-filled workspace. The swimmer has a diameter of 2.5 mm, a length of 6 mm, and is controlled by an external time-varying ... -
3FGL DEMOGRAPHICS OUTSIDE THE GALACTIC PLANE USING SUPERVISED MACHINE LEARNING: PULSAR AND DARK MATTER SUBHALO INTERPRETATIONS
(IOP, 2016-06-29)Nearly one-third of the sources listed in the Third Fermi Large Area Telescope (LAT) catalog (3FGL) remain unassociated. It is possible that predicted and even unanticipated gamma-ray source classes are present in these ... -
3FHL: The Third Catalog of Hard Fermi-LAT Sources
(IOP, 2017-09-27)We present a catalog of sources detected above 10 GeV by the Fermi Large Area Telescope (LAT) in the first 7 years of data using the Pass 8 event-level analysis. This is the Third Catalog of Hard Fermi-LAT Sources (3FHL), ... -
