NuSTAR Detection of X-rays Concurrent with Gamma Rays in the Nova V5855 Sgr
Thomas Nelson, Koji Mukai, Kwan-Lok Li +7
We report the first detection of hard (>10 keV) X-ray emission simultaneous with gamma rays in a nova eruption. Observations of the nova V5855 Sgr carried out with the NuSTAR satel…
On the broad-band synchrotron spectra of pulsar wind nebulae
Siyao Xu, Noel Klingler, Oleg Kargaltsev +1
As shown by broad-band observations, pulsar wind nebulae (PWNe) are characterized by a broken power-law spectrum of synchrotron emission. Based on the modern magnetohydrodynamic (M…

Dense matter with eXTP
Anna L. Watts, Wenfei Yu, Juri Poutanen +73
In this White Paper we present the potential of the Enhanced X-ray Timing and Polarimetry (eXTP) mission for determining the nature of dense matter; neutron star cores host an extr…
A -ray determination of the Universe's star-formation history
LAT Collaboration, M. Ajello, K. Helgason +4
The light emitted by all galaxies over the history of the Universe produces the extragalactic background light (EBL) at ultraviolet, optical, and infrared wavelengths. The EBL is a…
Unresolved Gamma-Ray Sky through its Angular Power Spectrum
M. Ackermann, M. Ajello, L. Baldini +107
The gamma-ray sky has been observed with unprecedented accuracy in the last decade by the Fermi large area telescope (LAT), allowing us to resolve and understand the high-energy Un…
Linear polarization in gamma-ray burst prompt emission
Ramandeep Gill, Jonathan Granot, Pawan Kumar
Despite being hard to measure, GRB prompt -ray emission polarization is a valuable probe of the dominant emission mechanism and the outflow's composition and angular structure.…
Possible phase-dependent absorption feature in the x-ray spectrum of the middle-aged PSR J0659+1414
Prakash Arumugasamy, Oleg Kargaltsev, Bettina Posselt +2
We report on the energy-resolved timing and phase-resolved spectral analysis of X-ray emission from PSR J0659+1414 observed with XMM-Newton and NuSTAR. We find that the new data ru…
The Variable Pulsar Wind Nebula of PSR J1809-1917
Noel Klingler, Oleg Kargaltsev, George G. Pavlov +1
PSR J1809-1917 is a young ( kyr) energetic ( erg s) radio pulsar powering a pulsar wind nebula (PWN). We report on the results of three Chand…
Neutron Star Mergers Might not be the Only Source of r-Process Elements in the Milky Way
Benoit Côté, Marius Eichler, Almudena Arcones +8
Probing the origin of r-process elements in the universe represents a multi-disciplinary challenge. We review the observational evidence that probe the properties of r-process site…
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…
The luminous host galaxy, faint supernova and rapid afterglow rebrightening of GRB 100418A
A. de Ugarte Postigo, C. C. Thoene, K. Bensch +35
Long gamma-ray bursts give us the chance to study both their extreme physics and the star-forming galaxies in which they form. GRB 100418A, at a z = 0.6239, had a bright optical an…
Chandra X-ray Observatory and Hubble Space Telescope observations of the intermediate-age cluster GLIMPSE-C01
Jeremy Hare, Oleg Kargaltsev, Blagoy Rangelov
We report the results of Hubble Space Telescope (HST) and Chandra X-ray Observatory (CXO) observations of the GLIMPSE-C01 (hereafter GC01) star cluster. Color-magnitude and color-c…
The Bright X-Ray Source in NGC 3413
E. Sonbas, K. S. Dhuga, E. Göğüş
The emission-line dwarf galaxy NGC 3413 is known to host a bright X-ray source near its optical center. The 0.3-10 keV luminosity of this source is estimated to be approximately 10…
Observational constraints on the structure of gamma-ray burst jets
Paz Beniamini, Ehud Nakar
Motivated by GW170817 we examine constraints that observations put on the angular structure of long gamma-ray burst (GRB) jets. First, the relatively narrow observed distribution o…
A lesson from GW170817: most neutron star mergers result in tightly collimated successful GRB jets
Paz Beniamini, Maria Petropoulou, Rodolfo Barniol Duran +1
The joint detection of gravitational waves (GWs) and -rays from a binary neutron-star (NS) merger provided a unique view of off-axis GRBs and an independent measurement of the N…
