Illuminating M82: Simulating X-ray Emission from Galactic Winds in a Starburst Galaxy
Allison Lin, Lachlan Lancaster, Viraj Pandya +6
We generate mock X-ray observations from a suite of idealized high-resolution ( pc), tall-box ( kpc) simulations of star formation driven gala…

Lomb-Scargle periodograms struggle with non-sinusoidal supermassive BH binary signatures in quasar lightcurves
Allison Lin, Maria Charisi, Zoltan Haiman
Supermassive black hole binary (SMBHB) systems are expected to form as a consequence of galaxy mergers. At sub-parsec separations, SMBHBs can be identified as quasars with periodic…

Periodicity significance testing with null-signal templates: reassessment of PTF's SMBH binary candidates
Jakob Robnik, Adrian E. Bayer, Maria Charisi +3
Periodograms are widely employed for identifying periodicity in time series data, yet they often struggle to accurately quantify the statistical significance of detected periodic s…
