EVOLUTION OF THE CRAB NEBULA IN A LOW ENERGY SUPERNOVA [PDF]
, 2015 The nature of the supernova leading to the Crab Nebula has long been controversial because of the low energy that is present in the observed nebula.

The Effect of Seductive Details on Knowledge Retention in Physics Videos: A Mixed Methods Study
Journal of Research in Science Teaching, EarlyView.ABSTRACT Research reports that interesting but irrelevant information, seductive details, in teaching material can impede learning. In science education, the inclusion of historical narratives in lessons to promote interest has been recommended but may hinder learning.

Circumstellar Disk Accretion Across the Lagoon Nebula: The Influence of Environment and Stellar Mass
The Astronomical JournalPre-main-sequence disk accretion is pivotal for determining the final stellar properties and the early conditions for close-in planets. We aim to establish the impact of internal (stellar mass) and external (radiation field) parameters on the disk ...

Constraints on particle acceleration sites in the Crab nebula from relativistic magnetohydrodynamic simulations [PDF]
, 2015 The Crab Nebula is one of the most efficient accelerators in the Galaxy and the only galactic source showing direct evidence of PeV particles. In spite of this, the physical process behind such effective acceleration is still a deep mystery.

Disrupting Pedagogies: Translating Disrupting Into Instructional Strategies
New Directions for Teaching and Learning, EarlyView.ABSTRACT This chapter demonstrates the possibilities when a Disrupting the Disciplines framework is used alongside the Decoding the Disciplines framework to directly address teaching bottlenecks related to racism, colonialism, and implicit bias. It describes the benefits of Disrupting interviews for exploring bottlenecks in classroom instructional ...

On the possible wind nebula of magnetar Swift J1834.9-0846: a magnetism-powered synchrotron nebula [PDF]
, 2016 Recently, the magnetar Swift J1834.9$-$0846 is reported to have a possible wind nebula. It is shown that both the magnetar and its wind nebula are understandable in the wind braking scenario. The magnetar's rotational energy loss rate is not enough to power the particle luminosity. The required particle luminosity should be about $10^{36} \,\rm erg \,s^

OVERTURNING THE CASE FOR GRAVITATIONAL POWERING IN THE PROTOTYPICAL COOLING LYα NEBULA [PDF]
, 2015 The Nilsson et al. Lyα nebula has often been cited as the most plausible example of an Lyα nebula powered by gravitational cooling. In this paper, we bring together new data from the Hubble Space Telescope and the Herschel Space Observatory as well as ...
