Triple- and quadruple-escape peaks in HPGe detectors: Experimental observation and Monte Carlo simulation
(ELSEVIER SCIENCE BV, 2010)
The triple- and quadruple-escape peaks of 6.128 MeV photons from the (19)F(p,alpha gamma)(16)O nuclear reaction were observed in an HPGe detector. The experimental peak areas, measured in spectra projected with a restriction ...

Cosmic-ray production from neutron escape in microquasar jets
(EDP Sciences, 2021-06)
Context. The origin of Galactic cosmic rays remains a matter of debate, but supernova remnants are commonly considered to be the main place where high-energy cosmic rays are accelerated. Nevertheless, current models predict ...
Ly alpha EMITTER GALAXIES AT z similar to 2.8 IN THE EXTENDED CHANDRA DEEP FIELD SOUTH. I. TRACING THE LARGE-SCALE STRUCTURE VIA Ly alpha IMAGING
(IOP PUBLISHING LTD, 2016)
We present a narrowband survey with three adjacent filters for z - 2.8-2.9 Lyman alpha (Ly alpha) emitter (LAE) galaxies in the Extended Chandra Deep Field South (ECDFS), along with spectroscopic follow-up. With a complete ...
Chemodynamics of green pea galaxies - I. Outflows and turbulence driving the escape of ionizing photons and chemical enrichment
(Wiley Blackwell Publishing, Inc, 2020-05)
We investigate the ionized gas kinematics, physical properties, and chemical abundances of Sloan Digital Sky Survey J142947, a Green Pea galaxy at redshift z ∼ 0.17 with strong, double-peak Ly α emission and indirect ...
Observation of double electron-positron pair production by gamma rays reexamined
(AMER PHYSICAL SOC, 2009)
An experiment was conducted to observe triple- and quadruple-escape peaks, at a photon energy equal to 6.128 MeV, in the spectra recorded with a high-purity Ge detector working in coincidence with six bismuth germanate ...
The Fast Declining Type Ia Supernova 2003gs, and Evidence for a Significant Dispersion in Near-Infrared Absolute Magnitudes of Fast Decliners at Maximum Light
(2009)
We obtained optical photometry of SN 2003gs on 49 nights, from 2 to 494 days after T(B_max). We also obtained near-IR photometry on 21 nights. SN 2003gs was the first fast declining Type Ia SN that has been well observed ...
