All We Are Is Dust In The WIM: Constraints on Dust Properties in the Milky Way's Warm Ionized Medium
J. L. West, B. M. Gaensler, M. -A. Miville-Deschênes +5
We present a comparison of the presence and properties of dust in two distinct phases of the Milky Way's interstellar medium: the warm neutral medium (WNM) and the warm ionized med…
Intrinsic Emission of PSR B1937+21 at 327 MHz
Nikhil Mahajan, Marten H. van Kerkwijk
At 327 MHz, the observed emission of PSR B1937+21 is greatly affected by scattering in the interstellar medium, on a timescale of order the pulse period. We use the bright impulsiv…
Using Giant Pulses to Measure the Impulse Response of the Interstellar Medium
Nikhil Mahajan, Marten H. van Kerkwijk
Giant pulses emitted by PSR B1937+21 are bright, intrinsically impulsive bursts. Thus, the observed signal from a giant pulse is a noisy but direct measurement of the impulse respo…
Resolving the Emission Regions of the Crab Pulsar's Giant Pulses II. Evidence for Relativistic Motion
Rebecca Lin, Marten H. van Kerkwijk, Robert Main +3
The Crab Pulsar is the prime example of an emitter of giant pulses. These short, very bright pulses are thought to originate near the light cylinder, at from…
Mode changing and giant pulses in the millisecond pulsar PSR B1957+20
Nikhil Mahajan, Marten H. van Kerkwijk, Robert Main +1
Many radio pulsars have stable pulse profiles, but some exhibit mode changing where the profile switches between two or more quasi-stable modes of emission. So far, these effects h…
Pulsar emission amplified and resolved by plasma lensing in an eclipsing binary
Robert Main, I-Sheng Yang, Victor Chan +6
Radio pulsars scintillate because their emission travels through the ionized interstellar medium via multiple paths, which interfere with each other. It has long been realized that…
Descattering of Giant Pulses in PSR B1957+20
Robert Main, Marten van Kerkwijk, Ue-Li Pen +2
The interstellar medium scatters radio waves which causes pulsars to scintillate. For intrinsically short bursts of emission, the observed signal should be a direct measurement of…
Stability of the Kepler-11 System and its Origin
Nikhil Mahajan, Yanqin Wu
A significant fraction of Kepler systems are closely-packed, largely coplanar and circular. We study the stability of a 6-planet system, Kepler-11, to gain insights on the dynamics…
