MULTIWAVELENGTH AND MULTIMESSENGER OBSERVATIONS OF BLAZARS AND THEORETICAL MODELING: BLAZARS AS ASTROPHYSICAL NEUTRINO SOURCES.

Publication Type:Conference

Source(s):Acta Physica Polonica B, Proceedings Supplement. 2022, Vol. 15 Issue 3, p1-18. 18p.

Abstract:This contribution reviews recent advances in the possible identification of blazars as potential sources of at least some of the very-high-energy neutrinos detected by the IceCube neutrino detector at the South Pole. The basic physical requirements for...

SEARCH FOR COSMIC RAY BURSTS AT PEV ENERGIES.

Publication Type:Conference

Source(s):Acta Physica Polonica B, Proceedings Supplement. 2022, Vol. 15 Issue 3, p1-8. 8p.

Abstract:Over the past forty years, there have been occasional reports of the observations of 'bursts' by small air-shower arrays operating at energies of about 1 PeV. These would seem to be of astrophysical origin and related to the thrust of studies pursued b...

The SHADES neutron detection array.

Publication Type:Conference

Source(s):EPJ Web of Conferences. 2/24/2022, Vol. 260, p1-5. 5p.

Abstract:The detection of neutrons in low energy astrophysics poses two main problems: low cross section measurement requires high detection efficiency and ideally, beam-induced and external neutron backgrounds should be identified through an energy sensitive d...

First direct limit on the 395 keV resonance of the 22Ne(α, γ)26Mg reaction.

Publication Type:Conference

Source(s):EPJ Web of Conferences. 2/24/2022, Vol. 260, p1-6. 6p.

Abstract:The 22Ne(α, γ)26Mg reaction (Q = 10614.74 keV) competes with the 22Ne(α, n)25Mg reaction (Q = −478.34 keV) which is the main source of neutrons for the s-process in low-mass Asymptotic Giant Branch and massive stars. The cross sections of these reactio...

Measurement and analysis techniques for a study of 12C(p,γ) and 13C(p,γ) deep underground.

Publication Type:Conference

Source(s):EPJ Web of Conferences. 2/24/2022, Vol. 260, p1-4. 4p.

Abstract:The 12C(p,γ) and 13C(p,γ) reaction cross sections are currently under investigation in the low-background environment of the Laboratory for Underground Nuclear Astrophysics. Both reactions are being studied using different types of solid targets, and e...

Cross-section measurements relevant for the astrophysical p process at the University of Cologne.

Publication Type:Conference

Source(s):EPJ Web of Conferences. 2/24/2022, Vol. 260, p1-4. 4p.

Abstract:The astrophysical p process unites all processes that have been introduced to explain the abundance of a group of 30 to 35 neutron-deficient nuclei which are referred to as p nuclei. In general, these p processes include large networks of nuclear reacti...

Direct measurement of the 19F(p, αγ)16O reaction in JUNA.

Publication Type:Conference

Source(s):EPJ Web of Conferences. 2/24/2022, Vol. 260, p1-4. 4p.

Abstract:The 19F(p, αγ)16O reaction is of crucial importance for Galactic 19F abundances and CNO cycle loss in first generation Population III stars. Due to its extremely small cross sections, the 19F(p, αγ)16O reaction has not been measured in the low energy p...

Commissioning of Underground Nuclear Astrophysics Experiment JUNA in China.

Publication Type:Conference

Source(s):EPJ Web of Conferences. 2/24/2022, Vol. 260, p1-6. 6p.

Abstract:Underground Nuclear Astrophysics Experiment in China (JUNA) has been commissioned by taking the advantage of the ultra-low background in Jinping underground lab. High current mA level 400 KV accelerator with an ECR source and BGO detectors were commiss...

Axion-like Particles from Nearby Type Ia Supernovae.

Publication Type:Conference

Source(s):EPJ Web of Conferences. 2/24/2022, Vol. 260, p1-4. 4p.

Abstract:Axion-like particles (ALPs) are a class of hypothetical pseudo-scalar particles and can be created in hot astrophysical plasma through the interaction between photons. I calculate the production of ALPs in type Ia supernovae. It is found that many ALPs...
