Accompanying slides for the MAGIC publication "Very-high-energy gamma-ray observations of the Type Ia Supernova SN 2014J with the MAGIC telescopes"

open access: yes, 2017
The manuscript reports the observations on SN 2014J, the closest Type Ia Supernova in the last four decades, located in the starburst galaxy M82. This result corresponds to the first upper limits on the very-high-energy gamma-ray emission from this type ...

Threshold Protocol Game on Graphs with Magic Square-Generalization Labelings

open access: yesGames
Graphical games describe strategic interactions among a specified network of players. The threshold protocol game is a graphical game that models the adoption of a lesser-used product in a population when individuals benefit by using the same product ...

Bounds of Strong EMT Strength for certain Subdivision of Star and Bistar

open access: yesOpen Mathematics, 2018
A super edge-magic total (SEMT) labeling of a graph ℘(V, E) is a one-one map ϒ from V(℘)∪E(℘) onto {1, 2,…,|V (℘)∪E(℘) |} such that ∃ a constant “a” satisfying ϒ(υ) + ϒ(υν) + ϒ(ν) = a, for each edge υν ∈E(℘), moreover all vertices must receive the ...

Integer-Magic Spectra of Sun Graphs

open access: yes, 2013
國科會研究計畫:NSC 98-2115-M-032-005-MY3Let N be the set of all positive integers, and Zn={0, 1, 2, …, n-1}. For any h ∈ N, a graph G=(V,E) is said to be Zh-magic if there exists a labeling f : E → Zh\{0} such that induced vertex labeling f+ : V → Zh, defined ...

Hyper Face-Magic Graphs

open access: yesTheory and Applications of Graphs
For a planar graph G of order n, let F(G) be the set of all faces of G embedded into R 2 , including the exterior face. A bijective vertex labeling f : V (G) → {1, 2, ..., n} induces a face labeling f ∗ : F(G) → N defined by setting f ∗ (F) equal to the ...

Nonstabilizerness in open XXZ spin chains: Universal scaling and dynamics

open access: yesPhysical Review Research
Magic, or nonstabilizerness, is a crucial quantum resource, yet its dynamics in open quantum systems remain largely unexplored. We investigate magic in the open XXZ spin chain under either boundary gain and loss or bulk dephasing using the stabilizer ...

Odd order C₄-face-magic projective grid graphs

open access: yesElectronic Journal of Graph Theory and Applications
For a graph G = (V, E) embedded in the projective plane, let F(G) denote the set of faces of G. Then, G is called a Cₙ-face-magic projective graph if there exists a bijection f: V(G) → {1, 2, …, |V(G)|} such that for any F ∈ F(G) with F ≅ Cₙ, the sum of ...

Constraining the Dark Matter decay lifetime with very deep observations of the Perseus cluster with the MAGIC telescopes [PDF]

open access: yes, 2015
We present preliminary results on Dark Matter searches from observations of the Perseus galaxy cluster with the MAGIC Telescopes. MAGIC is a system of two Imaging Atmospheric Cherenkov Telescopes located in the Canary island of La Palma, Spain. Galaxy
