First Demonstration of the HeRALD Superfluid Helium Detector Concept

R. Anthony-Petersen, A. Biekert, C. L. Chang +33

The SPICE/HeRALD collaboration is performing R&D to enable studies of sub-GeV dark matter models using a variety of target materials. Here we report our recent progress on instrume…

EMPRESS. XIV. Strong High Ionization Lines of Young Galaxies at $z = 0 - 8$ : Ionizing Spectra Consistent with the Intermediate Mass Black Holes with $M_{BH} \sim 1 0^{3} - 1 0^{6} M_{⊙}$

Shun Hatano, Masami Ouchi, Hiroya Umeda +16

We present ionizing spectra estimated at 13.6--100 eV for ten dwarf galaxies with strong high ionization lines of He {\sc {ii}} $λ$ 4686 and [Ne {\sc{v}}] $λ$ 3426 ([Ne {\sc{iv}}] $λ$ 24…

A portable and high intensity 24 keV neutron source based on $^{124}$ Sb- $^{9}$ Be photoneutrons and an iron filter

A. Biekert, C. Chang, L. Chaplinsky +27

A portable monoenergetic 24 keV neutron source based on the $^{124}$ Sb- $^{9}$ Be photoneutron reaction and an iron filter has been constructed and characterized. The coincidence of th…
