I don't like pipes. I think this is idiomatic R:
mbhps |> select(mopfama) |> mutate(mopfama = ifelse(mopfama <0, NA, mopfama)) -> tabdat
To my old eyes that seems a weird way of writing nested functions, and this would be more sensible:
tabdat <- mutate(select(mbhps, mopfama), mopfama = ifelse(mopfama <0, NA, mopfama))
This dplyr-piping is what used to be called syntactic sugar. I think its purpose is to make code look more like a command languag…

Simulation-based Inference of Massive Black Hole Binaries using Sequential Neural Likelihood
We propose a machine learning-based approach for parameter estimation of Massive Black Hole Binaries (MBHBs), leveraging normalizing flows to approximate the likelihood function. By training these flows on simulated data, we can generate posterior samples via Markov Chain Monte Carlo with a relatively reduced computational cost. Our method enables iterative refinement of smaller models targeting specific MBHB events, with significantly fewer waveform template evaluations. However, dimensionalit…

Identifying massive black hole binaries via light curve variability in optical time-domain surveys
Accreting massive black hole binaries (MBHBs) often display periodic variations in their emitted radiation, providing a distinctive signature for their identification. In this work, we explore the MBHBs identification via optical variability studies by simulating the observations of the LSST survey. To this end, we generate a population of MBHBs using the L-Galaxies semi-analytical model, focusing on systems with observed orbital periods $\leq$ 5 years. This ensures that at least two complete c…

The Doppler boosted LISA response to gravitational waves
The future space-based gravitational wave observatory LISA is expected to detect massive black hole binaries (MBHBs) with high signal-to-noise ratios (SNRs), ranging up to thousands. Such high-precision observations require accurate modeling of the detector response. However, current derivations of the response function neglect the motion of the spacecraft during light travel time, omitting velocity-dependent terms of order $β= v/c \sim 10^{-4}$. In this work, we derive the velocity-dependent …
