Segregated configurations involving the square root of the laplacian and their free boundaries
Daniela De Silva, Susanna Terracini
We study the local structure and the regularity of free boundaries of segregated critical configurations involving the square root of the laplacian. We develop an improvement of fl…
Unfolding overlapped slitless imaging spectrometer data for extended sources
Amy Winebarger, Mark Weber, Christian Bethge +9
Slitless spectrometers can provide simultaneous imaging and spectral data over an extended field of view, thereby allowing rapid data acquisition for extended sources. In some inst…
Periastron Observations of TeV Gamma-Ray Emission from a Binary System with a 50-year Period
The VERITAS Collaboration, A. U. Abeysekara, W. Benbow +212
We report on observations of the pulsar / Be star binary system PSR J2032+4127 / MT91 213 in the energy range between 100 GeV and 20 TeV with the VERITAS and MAGIC imaging atmosphe…
A search for black hole microlensing signatures in globular cluster NGC 6656 (M 22)
N. Kains, A. Calamida, K. C. Sahu +3
We report the results of a study aiming to detect signs of astrometric microlensing caused by an intermediate-mass black hole (IMBH) in the center of globular cluster M 22 (NGC 665…
Observing the Energetic Universe at Very High Energies with the VERITAS Gamma Ray Observatory
R. Mukherjee
Very high energy gamma-ray observations offer indirect methods for studying the highest energy cosmic rays in our Universe. The origin of cosmic rays at energies greater than $10^{…
VERITAS and Fermi-LAT observations of new HAWC sources
VERITAS Collaboration, A. U. Abeysekara, A. Archer +280
The HAWC (High Altitude Water Cherenkov) collaboration recently published their 2HWC catalog, listing 39 very high energy (VHE; >100~GeV) gamma-ray sources based on 507 days of obs…
