The GALAH Survey and Symbiotic Stars. I. Discovery and follow-up of 33 candidate accreting-only systems
U. Munari, G. Traven, N. Masetti +14
We have identified a first group of 33 new candidates for symbiotic stars (SySt) of the accreting-only variety among the 600,255 stars so far observed by the GALAH high-resolution…
Photometry and spectroscopy of the new symbiotic star 2SXPS J173508.4-292958
U. Munari, P. Valisa, A. Vagnozzi +3
We present and discuss the results of our photometric and spectroscopic monitoring of 2SXPS J173508.4-292958 carried out from April to August 2020. This X-ray source, in the foregr…
Fermi-LAT Observations of V549 Vel 2017: a Sub-Luminous Gamma-Ray Nova?
Kwan-Lok Li, Franz-Josef Hambsch, Ulisse Munari +4
We report on the Fermi-LAT detection (with ~5.7 sigma significance) as well as the multi-wavelength analysis of the 2017 nova eruption V549 Vel. Unlike the recent shock-powered nov…
The path to Z And-type outbursts: The case of V426 Sagittae (HBHA 1704-05)
A. Skopal, S. Yu. Shugarov, U. Munari +16
The star V426 Sge (HBHA~1704-05), originally classified as an emission-line object and a semi-regular variable, brightened at the beginning of August 2018, showing signatures of a…
First detection of the Crab Nebula at TeV energies with a Cherenkov telescope in a dual-mirror Schwarzschild-Couder configuration: the ASTRI-Horn telescope
S. Lombardi, O. Catalano, S. Scuderi +89
We report on the first detection of very high-energy (VHE) gamma-ray emission from the Crab Nebula by a Cherenkov telescope in dual-mirror Schwarzschild-Couder (SC) configuration.…
On Characteristics of Hyperfields Obtained as Quotients of Finite Fields
Antonio Frigo, Hahn Lheem, Dylan Liu
Hyperstructures are a natural extension of regular algebraic structures in which one of the operations, known as the hyperoperation, is multivalued; a hyperfield is such an extensi…
