Template bank for spinning compact binary mergers in the second observation run of Advanced LIGO and the first observation run of Advanced Virgo
Debnandini Mukherjee, Sarah Caudill, Ryan Magee +25
We describe the methods used to construct the aligned-spin template bank of gravitational waveforms used by the GstLAL-based inspiral pipeline to analyze data from the second obser…
Disentangling interstellar plasma screens with pulsar VLBI: Combining auto- and cross-correlations
Dana Simard, Ue-Li Pen, Visweshwar Ram Marthi +1
Pulsar scintillation allows a glimpse into small-scale plasma structures in the interstellar medium, if we can infer their properties from the scintillation pattern. With Very Long…
The Wide Integral Field Infrared Spectrograph: Commissioning Results and On-sky Performance
Suresh Sivanandam, Dae-Sik Moon, R. Elliot Meyer +11
We have recently commissioned a novel infrared ( m) integral field spectrograph (IFS) called the Wide Integral Field Infrared Spectrograph (WIFIS). WIFIS is a unique in…
Post-correlation beamformer for time-domain studies of pulsars and transients
Jayanta Roy, Jayaram N. Chengalur, Ue-Li Pen
We present a detailed analysis of post-correlation beamforming (i.e. beamforming which involves only phased sums of the correlation of the voltages of different antennas in an arra…
Spectral Kurtosis Based RFI Mitigation for CHIME
Jacob Taylor, Nolan Denman, Kevin Bandura +5
We present the implementation of a spectral kurtosis based Radio Frequency Interference detection system on the CHIME instrument and its reduced-scale pathfinder. Our implementatio…
Identifying transient and variable sources in radio images
Antonia Rowlinson, Adam J. Stewart, Jess W. Broderick +16
With the arrival of a number of wide-field snapshot image-plane radio transient surveys, there will be a huge influx of images in the coming years making it impossible to manually…
