Internal Heating of Old Neutron Stars: Contrasting Different Mechanisms
, 2010 The thermal emission detected from the millisecond pulsar J0437-4715 is not explained by standard cooling models of neutron stars without a heating mechanism.

Recent Advancements in the Treatment of Age‐Related Macular Degeneration
Med Research, EarlyView.ABSTRACT Age‐related macular degeneration (AMD) is a prevalent cause of visual impairment and blindness among the elderly. AMD can be categorized into two subtypes: “wet” and “dry.” Current treatments for wet AMD mainly involve anti‐vascular endothelial growth factor (VEGF) drugs, and there are three U.S.

Pulsar Results with the Fermi Large Area Telescope
, 2010 The launch of the Fermi Gamma-ray Space Telescope has heralded a new era in the study of gamma-ray pulsars. The population of confirmed gamma-ray pulsars has gone from 6-7 to more than 60, and the superb sensitivity of the Large Area Telescope (LAT) on ...

Two Micron‐Size Dark Dimensions
Fortschritte der Physik, EarlyView.Abstract Two extra dimensions of micron scale might simultaneously address the gauge and cosmological hierarchy problems. In this paper various observational bounds in scenarios with one and two large extra dimensions are examined, to see if they are compatible with the micron scale.

Equilibrium spin pulsars unite neutron star populations
, 2013 Many pulsars are formed with a binary companion from which they can accrete matter. Torque exerted by accreting matter can cause the pulsar spin to increase or decrease, and over long times, an equilibrium spin rate is achieved.

Properties and observability of glitches and anti-glitches in accreting pulsars [PDF]
, 2015 Several glitches have been observed in young, isolated radio pulsars, while a clear detection in accretion-powered X-ray pulsars is still lacking. We use the Pizzochero snowplow model for pulsar glitches as well as starquake models to determine for the ...

Fortschritte der Physik, EarlyView.Abstract In this study, the properties, equilibrium, and stability of compact objects within the framework of teleparallel gravity with the generalized MIT bag model are investigated. By incorporating the modified field equations, the influence of the generalized bag constant on the structure and physical characteristics of quark stars and neutron ...

Nesting ecology of an ice‐associated seabird, Kittlitz's murrelet, at the northern edge of its range
Wildlife Society Bulletin, EarlyView.We studied the Kittlitz's murrelet, an ice‐associated seabird of conservation concern, at the northern edge of its range. Over a 2‐year period, we estimated nest density and success at 2 sites, captured and telemetered nesting murrelets, and tested the use of a thermal camera to improve nest detection.

A New X-Ray Census of Rotation Powered Pulsars
The Astrophysical JournalTo date, over 4000 pulsars have been detected. In this study, we identify 231 X-ray counterparts of Australia Telescope National Facility (ATNF) pulsars by performing a spatial cross match across the Chandra, XMM-Newton observational catalogs.
