Detectability of continuous gravitational waves from planetary-mass companions orbiting compact stars

Astronomy & Astrophysics
Binary systems with ultrashort-period planetary-mass companions are expected to radiate continuous gravitational waves (GWs). However, earlier studies found that the detectability of such systems by the Laser Interferometer Space Antenna (LISA) is ...

PARTNeR for Teaching and Learning Radio Astronomy Basics [PDF]

, 2010
NASA has three satellite tracking stations around the world: CDSCC (Canberra, Australia), GDSCC (Goldstone, USA) and MDSCC (Madrid, Spain). One of the antennas located at MDSCC, DSS-61, is not used for satellite tracking any more and thanks to an ...

The ONs and OFFs of Pulsar Radio Emission: Characterizing the Nulling Phenomenon

The Astrophysical Journal
Radio emission from pulsars is known to exhibit a diverse range of emission phenomena, among which nulling, where the emission becomes temporarily undetectable, is an intriguing example.

Discovery and Follow-up of a Quasiperiodically Nulling and Subpulse Drifting Pulsar with the Murchison Widefield Array

The Astrophysical Journal
The phenomenon of pulsar nulling, where pulsars temporarily and stochastically cease their radio emission, is thought to be indicative of a “dying” pulsar, where radio emission ceases entirely.

RFI subspace estimation techniques for new generation radio telescopes [PDF]

, 2012
International audienceRadio astronomical data are increasingly corrupted by human telecommunication activities. Therefore, Radio Frequency Interferences (RFI) mitigation becomes an important step in the data processing flow, in particular for phased ...

The State of Astronomy Education in the U.S. [PDF]

, 1996
I would like to set the scene for the discussion that will follow in this book and bring up a few disturbing points which I believe any discussion about astronomy education will ultimately have to address.
