A new method to quantify and reduce projection error in whole-solar-active-region parameters measured from vector magnetograms
David A. Falconer, Sanjiv K. Tiwari, Ronald L. Moore +1
Projection error limits the use of vector magnetograms of active regions (ARs) far from disk center. In this Letter, for ARs observed up to 60o from disk center, we demonstrate a m…
From ultraluminous X-ray sources to ultraluminous supersoft sources: NGC 55 ULX, the missing link

In recent work with high-resolution grating spectrometers (RGS) aboard XMM-Newton Pinto et al. (2016) have discovered that two bright and archetypal ultraluminous X-ray sources (UL…
Parameter estimation for gravitational-wave bursts with the BayesWave pipeline
Bence Bécsy, Peter Raffai, Neil J. Cornish +6
We provide a comprehensive multi-aspect study on the performance of a pipeline used by the LIGO-Virgo Collaboration for estimating parameters of gravitational-wave bursts. We add s…
A Microfilament-Eruption Mechanism for Solar Spicules
Alphonse C. Sterling, Ronald L. Moore
Recent investigations indicate that solar coronal jets result from eruptions of small-scale chromospheric filaments, called minifilaments; that is, the jets are produced by scaled-…
Crossing the Eddington limit: examining disk spectra at high accretion rates
Andrew D. Sutton, Douglas A. Swartz, Timothy P. Roberts +3
The faintest ultraluminous X-ray sources (ULXs), those with 0.3-10 keV luminosities 1 < L_X/10^39 < 3 erg s^-1, tend to have X-ray spectra that are disk-like but broader than expec…
Miniature loops in the solar corona
Krzysztof Barczynski, Hardi Peter, Sabrina L. Savage
Magnetic loops filled with hot plasma are the main building blocks of the solar corona. Usually they have lengths of the order of the barometric scale height in the corona that is…
Geminga's puzzling pulsar wind nebula
B. Posselt, G. G. Pavlov, P. O. Slane +6
We report on six new Chandra observations of the Geminga pulsar wind nebula (PWN). The PWN consists of three distinct elongated structures - two pc long later…
Gravity Spy: Integrating Advanced LIGO Detector Characterization, Machine Learning, and Citizen Science
Michael Zevin, Scott Coughlin, Sara Bahaadini +15
(abridged for arXiv) With the first direct detection of gravitational waves, the Advanced Laser Interferometer Gravitational-wave Observatory (LIGO) has initiated a new field of as…
Magnetic Flux Cancellation as the Trigger of Solar Quiet-Region Coronal Jets
Navdeep K. Panesar, Alphonse C. Sterling, Ronald L. Moore +1
We report observations of ten random on-disk solar quiet region coronal jets found in high resolution Extreme Ultraviolet (EUV) images from the Solar Dynamics Observatory (SDO)/Atm…
Deep Chandra Observations of the Pulsar Wind Nebula Created by PSR B0355+54
Noel Klingler, Blagoy Rangelov, Oleg Kargaltsev +10
We report on Chandra X-ray Observatory (CXO) observations of the pulsar wind nebula (PWN) associated with PSR B0355+54 (eight observations with a 395 ks total exposure, performed o…
Vertical magnetic field gradient in the photospheric layers of sunspots
Jayant Joshi, Andreas Lagg, Johann Hirzberger +2
We investigate the vertical gradient of the magnetic field of sunspots in the photospheric layer. Independent observations were obtained with the SOT/SP onboard the Hinode spacecra…
A Comparison of Flare Forecasting Methods, I: Results from the "All-Clear" Workshop
G. Barnes, K. D. Leka, C. J. Schrijver +15
Solar flares produce radiation which can have an almost immediate effect on the near-Earth environment, making it crucial to forecast flares in order to mitigate their negative eff…
Large Observatory for x-ray Timing (LOFT-P): A Probe-classs Mission Concept Study
Colleen A. Wilson-Hodge, Paul S. Ray, Deepto Chakrabarty +31
LOFT-P is a concept for a NASA Astrophysics Probe-Class (<$1B) X-ray timing mission, based on the LOFT concept originally proposed to ESAs M3 and M4 calls. LOFT-P requires very lar…
Gravitational wave observations may constrain gamma-ray burst models: the case of GW 150914 - GBM
P. Veres, R. D. Preece, A. Goldstein +3
The possible short gamma-ray burst (GRB) observed by {\it Fermi}/GBM in coincidence with the first gravitational wave (GW) detection, offers new ways to test GRB prompt emission mo…
Critical-angle x-ray transmission grating spectrometer with extended bandpass and resolving power > 10,000
Ralf K. Heilmann, Alexander R. Bruccoleri, Jeffery Kolodziejczak +4
Several high priority subjects in astrophysics can be addressed by a state-of-the-art soft x-ray grating spectrometer (XGS). An Explorer-scale, large-area (> 1,000 cm2), high resol…
The Quiescent Intracluster Medium in the Core of the Perseus Cluster
Hitomi Collaboration, Felix Aharonian, Hiroki Akamatsu +213
Clusters of galaxies are the most massive gravitationally-bound objects in the Universe and are still forming. They are thus important probes of cosmological parameters and a host…
Solar Coronal Jets: Observations, Theory, and Modeling
