Falcon continuous gravitational wave atlas and large scale data analysis using MVL.

ORAL

Abstract

Continuous waves from non-axisymmetric neutron stars are orders of magnitude weaker than transient events from black hole and neutron star collisions. However, because continuous waves persist, it is possible to improve sensitivity by integrating months of data at a great computational cost. The latest Falcon search has produced an atlas containing results of such integrations for every direction on the sky and every analyzed band. Both upper limits and signal-to-noise ratios are provided. Some of the results have been followed up, but the majority are unexplored.

The atlas data is provided in a new MVL file format that allows analysis on small computers, such as your notebook. There is also an MVL version of Gaia DR3 data, which can be used to explore Falcon atlas, or on its own.

We will discuss how Falcon atlas can be used to conduct new searches, and show examples of using MVL files with data from Falcon atlas and Gaia DR3.
