The hyperluminous X‐ray source population
We have recently published a catalog of 1843 candidate ultraluminous X‐ray sources (ULXs). This is the largest catalog of ULXs to date and was built by cross‐correlating recent serendipitous source catalogs from the XMM‐Newton...

Texture Analysis of T1 weighted and fluid attenuated inversion recovery images detects abnormalities which correlate with disease progression in small vessel disease
Background and Purpose
MRI techniques may be useful to assess disease severity in cerebral small vessel disease (SVD), identify those individuals who are most likely to progress to dementia, monitor disease progression and act...
Cosmological distances with general-relativistic ray tracing
Abstract
In this work we present the first results from a new ray-tracing tool to calculate
cosmological distances in the context of fully nonlinear general relativity. We use...

Retrospective evaluation of hyperproteinorrachia without pleocytosis (albuminocytologic dissociation) and survival in dogs.
BACKGROUND: Hyperproteinorrachia (raised cerebrospinal fluid total protein [CSF-TP]) without pleocytosis (HP) (also known as albuminocytologic dissociation) is identified in dogs with different neurologic diseases. However, the...
Searching for axion-like particles with X-ray polarimeters
X-ray telescopes are an exceptional tool for searching for new fundamental physics. In particular, X-ray observations have already placed world-leading bounds on the interaction between photons and axion-like particles (ALPs)....
Dynamic structure elucidation of chemical reactivity by laser pulses and X-ray probes
Visualising chemical reactions by X-ray methods is a tantalising prospect. New light sources provide the prospect for studying atomic, electronic and energy transfers accompanying chemical change by X-ray spectroscopy and...
A long-lived neutron star merger remnant in GW170817
L. Piro, Bing Zhang, Eleanora Troja, Geoffrey Ryan, Hendrik Van Eerten, R Ricci, M. H. Wieringa, A. Tiengo, N Butler, S. B. Cenko, O. D. Fox, H. G. Khandrika, G. Novara, T. Sakamoto
Feb 01, 2019
Multimessenger observations of GW170817 have not conclusively established whether the merger remnant is a black hole (BH) or a neutron star (NS). We show that a long-lived magnetized NS with a poloidal field B ≈ 1012 G is fully...
The First High-contrast Images of X-Ray Binaries
Abstract
X-ray binaries provide exceptional laboratories for understanding the physics of matter under the most extreme conditions. Until recently, there were few, if any...

Relativistic X-Ray Reverberation from Super-Eddington Accretion Flow
X-ray reverberation is a powerful technique which maps out the structure of
the inner regions of accretion disks around black holes using the echoes of the
coronal emission reflected by the disk. While the theory of X-ray...
Pathogenic mtDNA mutations causing mitochondrial myopathy

Oct 01, 2019
Pathogenic mitochondrial tRNA (mt-tRNA) gene mutations represent a prominent cause of primary mitochondrial DNA (mtDNA)-related disease despite accounting for only 5%-10% of the mitochondrial genome.(1,2) Although some common...
