The cosmological standard model at present is widely accepted as containing mainly things we do not understand. In particular the appearance of a Cosmological Constant, or dark energy, is puzzling....
View ArticleCompton-Pair Production Space Telescope (ComPair) for MeV Gamma-ray Astronomy
The gamma-ray energy range from a few hundred keV to a few hundred MeV has remained largely unexplored, mainly due to the challenging nature of the measurements, since the pi- oneering, but limited,...
View ArticleFirst Results from HAWC on GRBs
In this contribution, the first results of HAWC, searching for VHE gamma-ray emission from gamma-ray bursts (GRBs) reported by $\mathit{Swift}$, are presented. The HAWC gamma-ray observatory is...

For MeV gamma-ray astronomy, we have developed an electron-tracking Compton camera (ETCC) as a MeV gamma-ray telescope capable of rejecting the radiation background and attaining the high sensitivity...
View ArticlePrecision cosmology with time delay lenses: high resolution imaging...
Lens time delays are a powerful probe of cosmology, provided that the gravitational potential of the main deflector can be modeled with sufficient precision. Recent work has shown that this can be...
View ArticleFATS: Feature Analysis for Time Series [Replacement]
In this paper, we present the FATS (Feature Analysis for Time Series) library. FATS is a Python library which facilitates and standardizes feature extraction for time series data. In particular, we...
