Brightest Cluster Galaxy ellipticity as proxy for halo shape: Orientation bias, assembly bias, and potential selection effects in SZ-selected clusters
Radhakrishnan Srinivasan, Tae-hyeon Shin, Anja von der Linden +93
The orientation of triaxial galaxy clusters with respect to the line-of-sight is expected to be one of the prime sources of scatter and potential bias in optical observables (e.g.,…
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…
A testing facility for AO on-sky demonstrations at the Copernico's Telescope within the ADONI framework
S. Chinellato, R. Ragazzoni, J. Farinato +21
In the context of ADONI - the ADaptive Optics National laboratory of INAF - we are arranging for a facility, accessible to the AO community, in which visiting multi-purpose instrum…
Photometric evolution of seven recent novae and the double component characterizing the lightcurve of those emitting in gamma rays
U. Munari, F. -J. Hambsch, A. Frigo
The BVI lightcurves of seven recent novae have been extensively mapped with daily robotic observations from Atacama (Chile). They are V1534 Sco, V1535 Sco, V2949 Oph, V3661 Oph, MA…
Photometric evolution of the 2016 outburst of recurrent Nova LMC 1968: the first three weeks
U. Munari, F. M. Walter, F. -J. Hambsch +1
Optical (BVRI) photometry of the first three weeks of the 2016 outburst of the recurrent Nova LMC 1968 is presented and discussed. The 2016 I-band light-curve is an exact replica,…
APASS Landolt-Sloan BVgri photometry of RAVE stars. I. Data, effective temperatures and reddenings
U. Munari, A. Henden, A. Frigo +24
We provide APASS photometry in the Landolt BV and Sloan g'r'i' bands for all the 425,743 stars included in the latest 4th RAVE Data Release. The internal accuracy of the APASS phot…
Photometric evolution, orbital modulation and progenitor of Nova Mon 2012
U. Munari, S. Dallaporta, F. Castellani +4
We present and discuss accurate and densely mapped BVRI lightcurves of the neon Nova Mon 2012, supplemented by the evolution in Stromgren b and y bands and in the integrated flux o…
