Evidence for an abundant old population of Galactic ultra long period magnetars and implications for fast radio bursts

jobovy/galpy 17 Oct 2022

Finally, we show that existing radio campaigns are biased against detecting objects like these and discuss strategies for future radio and X-ray surveys to identify more such objects.

candl: Cosmic Microwave Background Analysis with a Differentiable Likelihood

lbalkenhol/candl 24 Jan 2024

As such, a fully differentiable pipeline allows for a higher level of scrutiny; we argue that this is the paradigm shift required to leverage incoming data from ground-based experiments, which will significantly improve the cosmological parameter constraints from the Planck mission.

FREmu: Power Spectrum Emulator for $f(R)$ Gravity

astrobai/fremu 9 May 2024

To investigate gravity in the non-linear regime of cosmic structure using measurements from Stage-IV surveys, it is imperative to accurately compute large-scale structure observables, such as non-linear matter power spectra, for gravity models that extend beyond general relativity.
