Cosmology from One Galaxy in a Void?
The Astrophysical Journal LettersUnderstanding galaxy properties may be the key to unlocking some of the most intriguing mysteries of modern cosmology. Recent work relied on machine learning to extract cosmological constraints on Ω _m using only one galaxy.

No Evidence for Second-scale Periodicity in FRB 20201124A from 2021 April to June FAST Observations
The Astrophysical JournalFast radio bursts (FRBs) are bright and short radio flashes of cosmological origin. Although a great number of FRBs have been detected in the last two decades, their progenitors and the physical processes that create them are unknown.

Quasar variability: an astrostatistical challenge
, 2016 Variable behavior on all time scales seems to be ubiquitous phenomenon in almost all classes of active galactic nuclei. This work deals with two topics. One being detection of microvariability (intra-night variability) in the sources which are obscured and were believed to be non variable - type 2 quasars.

Comment on "Bayesian astrostatistics: a backward look to the future" by Tom Loredo, arXiv:1208.3036
, 2012 This short note points out two of the incongruences that I find in the Loredo (2012) comments on Andreon (2012), i.e. on my chapter written for the book "Astrostatistical Challenges for the New Astronomy". First, I find illogic the Loredo decision of putting my chapter among those presenting simple models, because one of the models illustrated in my ...

A Bias-corrected Luminosity Function for Red Supergiant Supernova Progenitor Stars
The Astrophysical Journal LettersThe apparent tension between the luminosity functions of red supergiant (RSG) stars and of RSG progenitors of Type II supernovae (SNe) is often referred to as the RSG problem and it motivated some to suggest that many RSGs end their life without an SN ...
