Irreducibility of the Tutte polynomial of an embedded graph
Joanna A. Ellis-Monaghan, Andrew J. Goodall, Iain Moffatt +2
We prove that the ribbon graph polynomial of a graph embedded in an orientable surface is irreducible if and only if the embedded graph is neither the disjoint union nor the join o…
The neutron star population in M28: a joint Chandra/GBT look at pulsar paradise
Eda Vurgun, Manuel Linares, Scott Ransom +7
We present the results of a deep study of the neutron star (NS) population in the globular cluster M28 (NGC 6626), using the full 330-ks 2002-2015 ACIS dataset from the Chandra X-r…
Characterisation of the MUSIC ASIC for large-area silicon photomultipliers for gamma-ray astronomy
Nicolas De Angelis, David Gascón, Sergio Gómez +3
Large-area silicon photomultipliers (SiPMs) are desired in many applications where large surfaces have to be covered. For instance, a large area SiPM has been developed by Hamamats…
Hubble Space Telescope survey of Magellanic Cloud star clusters. Photometry and astrometry of 113 clusters and early results
A. P. Milone, G. Cordoni, A. F. Marino +29
In the past years, we have undertaken an extensive investigation of LMC and SMC star clusters based on HST data. We present photometry and astrometry of stars in 101 fields observe…
Search for Na in novae supported by a novel method for measuring femtosecond nuclear lifetimes
C. Fougères, F. de Oliveira Santos, J. José +58
Classical novae are thermonuclear explosions in stellar binary systems, and important sources of Al and Na. While gamma rays from the decay of the former radioisotope…
Dirac Points Embedded in the Continuum
Pilar Pujol-Closa, Lluis Torner, David Artigas
Dirac points (DP) in Hermitian systems play a key role in topological phenomena. Their existence in non-Hermitian systems is then desirable, but the addition of loss or gain transf…
