Einstein@Home Searches for Gamma-Ray Pulsars in the Inner Galaxy

C. J. Clark, Mattia Di Mauro, Jason Wu, B. Allen et autres

Abstract The Fermi Large Area Telescope (LAT) has revealed a mysterious extended excess of GeV gamma-ray emission around the Galactic Center (GC), which can potentially be explained by unresolved emission from a population of pulsars, particularly millisecond pulsars (MSPs), in the Galactic …

Einstein@Home all-sky "bucket" search for continuous gravitational waves in LIGO O3 public data

Brian McGloughlin, B. Steltner, M. A. Papa, H.-B. Eggenstein et autres

We conduct an all-sky search for continuous gravitational waves using LIGO O3 public data from the Hanford and Livingston detectors. We search for nearly-monochromatic signals with frequencies $30\, \text{Hz} \leq f \leq 250\, \text{Hz}$ and spin-down $-2.7 \times 10^{-9}\, \text{Hz/s} \leq \dot{f} …

Results From an Einstein@Home Search for Continuous Gravitational Waves From G347.3 at Low Frequencies in LIGO O2 Data

J. Ming, M. A. Papa, H.-B. Eggenstein, B. Machenschalk et autres

Abstract We present results of a search for periodic gravitational wave signals with frequencies between 20 and 400 Hz from the neutron star in the supernova remnant G347.3-0.5 using LIGO O2 public data. The search is deployed on the volunteer computing project …

Einstein@Home discovery of the gamma-ray millisecond pulsar PSR J2039–5617 confirms its predicted redback nature

C. J. Clark, L. Nieder, Guillaume Voisin, B. Allen et autres

ABSTRACT The Fermi Large Area Telescope gamma-ray source 3FGL J2039.6–5618 contains a periodic optical and X-ray source that was predicted to be a ‘redback’ millisecond pulsar (MSP) binary system. However, the conclusive identification required the detection of pulsations from the putative MSP. …

Discovery of a Gamma-Ray Black Widow Pulsar by GPU-accelerated Einstein@Home

L. Nieder, C. J. Clark, D. Kandel, Roger W. Romani et autres

Abstract We report the discovery of 1.97 ms period gamma-ray pulsations from the 75 minute orbital-period binary pulsar now named PSR J1653−0158. The associated Fermi Large Area Telescope gamma-ray source 4FGL J1653.6−0158 has long been expected to harbor a binary millisecond pulsar. …

Results from an Einstein@Home search for continuous gravitational waves from Cassiopeia A, Vela Jr., and G347.3

J. Ming, M. A. Papa, Avinash Singh, H.-B. Eggenstein et autres

We report results of the most sensitive search to date for periodic gravitational waves from Cassiopeia A, Vela Jr., and G347.3 with frequency between 20 and 1500 Hz. The search was made possible by the computing power provided by the volunteers of …

Optimally setting up directed searches for continuous gravitational waves in Advanced LIGO O1 data

J. Ming, M. A. Papa, B. Krishnan, R. Prix et autres

In this paper we design a search for continuous gravitational waves from three supernova remnants: Vela Jr., Cassiopeia A (Cas A) and G347.3. These systems might harbor rapidly rotating neutron stars emitting quasiperiodic gravitational radiation detectable by the advanced LIGO detectors. Our …
