Ubiquitous Interstellar Neutral Helium Detected with JWST
Jane R. Rigby, D. Koutroumpa, M. Galeazzi +8
We report the discovery of ubiquitous neutral helium emission in sky spectra taken with JWST's NIRSpec instrument. The emission, with a wavelength of 1.0833 micron, resembles one o…
LEM All-Sky Survey: Soft X-ray Sky at Microcalorimeter Resolution
Ildar Khabibullin, Massimiliano Galeazzi, Akos Bogdan +23
The Line Emission Mapper (LEM) is an X-ray Probe with with spectral resolution ~2 eV FWHM from 0.2 to 2.5 keV and effective area >2,500 cm at 1 keV, covering a 33 arcmin diamet…
On the distance to the North Polar Spur and the local CO-H2 factor
R. Lallement, S. Snowden, K. D. Kuntz +4
Most models identify the X-ray bright North Polar Spur (NPS) with a hot interstellar (IS) bubble in the Sco-Cen star-forming region at 130 pc. An opposite view considers th…
A Deep XMM-Newton Survey of M33: Point Source Catalog, Source Detection and Characterization of Overlapping Fields
Benjamin F. Williams, Brian Wold, Frank Haberl +9
We have obtained a deep 8-field XMM-Newton mosaic of M33 covering the galaxy out to the D isophote and beyond to a limiting 0.2--4.5 keV unabsorbed flux of 510$^{-16…
The Solar Wind Charge-Exchange Production Factor for Hydrogen
K. D. Kuntz, Y. M. Collado-Vega, M. R. Collier +9
The production factor, or broad band averaged cross-section, for solar wind charge-exchange with hydrogen producing emission in the ROSAT 1/4 keV (R12) band is $3.8\pm0.2\times10^{…
A Newly Recognized Very Young Supernova Remnant in M83
William P. Blair, P. Frank Winkler, Knox S. Long +7
As part of a spectroscopic survey of supernova remnant candidates in M83 using the Gemini-South telescope and GMOS, we have discovered one object whose spectrum shows very broad li…
