Schwarzschild solution from a Raychaudhuri-Huygens relation
Maurice H. P. M. van Putten
Null-congruences encode the causal structure of spacetime, describing a phase space of radiation channels, whose expansion scalar satisfies the Raychaudhuri equation. In spheri…
Efficient searches of small signals across two-channel noisy data: a challenge in Big Data observations
Maryam Aghaei Abchouyeh, Maurice H. P. M. van Putten
Searching for novel small signals in noisy data is preferably pursued by correlation in two or more independently operating channels. Signals of potential interest exist in tails b…
Parameter-free prediction of the asymptotic acceleration scale confirmed by weak lensing
Maurice H. P. M. van Putten
The de Sitter transition scale to anomalous galaxy dynamics was previously derived from first principles based on the background Hubble expansion and the velocity o…
Multimessenger Constraints on the Central Engine in SN 2023ixf: Neutron Star or Black Hole?
Maryam Aghaei Abchouyeh, Maurice H. P. M. van Putten, Massimo Della Valle
The physical trigger of core-collapse supernova (CC-SNe) is a central theme in modern surveys of the transient Universe. A multi-messenger approach may provide a unique window to C…
Is Dark Energy Increasing or Decreasing in the Late Universe?
Maryam Aghaei Abchouyeh, Maurice H. P. M. van Putten
The concordance cosmological model CDM assumes dark energy to be a constant, consistent with early-time observations, evidenced by Planck-CDM analyses. However, in the face o…
The Hubble parameter of the Local Distance Ladder from dynamical dark energy with no free parameters
Maurice H. P. M. van Putten
Our cosmology contains Big Bang relic fluctuations by a loss of time-translation symmetry on a Hubble time scale. The contribution to the vacuum is identified with dynamical dark e…
Galaxy dynamics tracing quantum cosmology beyond CDM below the de Sitter scale of acceleration
Maurice H. P. M. van Putten
It is proposed that the baryonic Tully-Fisher relation (bTFR) and JWST 'Impossible galaxies' at cosmic dawn are unified in weak gravity by the trace of the Schouten tensor belo…
On the Hubble expansion in a Big Bang quantum cosmology
Maurice H. P. M. van Putten
The Hubble expansion of the Universe is considered in the classical limit of a Big Bang quantum cosmology. In an IR-consistent coupling to the the bare cosmological constant, we in…
Slide FFT on a homogeneous mesh in wafer-scale computing
Maurice H. P. M. van Putten, Leighton Wilson, Adam W. Lavely +1
Searches for signals at low signal-to-noise ratios frequently involve the Fast Fourier Transform (FFT). For high-throughput searches, we here consider FFT on the homogeneous mesh o…
The Fast and Furious in JWST high- galaxies
Maurice H. P. M. van Putten
Recent JWST surveys reveal a striking abundance of massive galaxies at cosmic dawn, earlier than predicted by CDM. The implied speed-up in galaxy formation by gravitational coll…
A unit of information in black hole evaporation
Maurice H. P. M. van Putten
Black holes evolve by evaporation of their event horizon. While this process is believed to be unitary, there is no consensus on the recovery of information in black hole entropy.…
Observational prospects of double neutrons star mergers and their multi-messenger afterglows: LIGO discovery power, event rates and diversity

The double neutron star (DNS) merger event GW170817 signifies the first multimessenger (MM) event with electromagnetic-gravitational (EM-GW) observations. LIGO-Virgo-KAGRA observat…
Central engine of GRB170817A: Neutron star versus Kerr black hole based on multimessenger calorimetry and event timing
Maurice H. P. M. van Putten, Massimo Della Valle
The central engine of GRB170817A post-merger to GW170817 is probed by GW-calorimetry and event timing, applied to a post-merger descending chirp which can potentially break the deg…

A bound on the cosmic opacity of unparticles from the CMB temperature
Maurice H. P. M. van Putten, Maryam Aghaei Abchouyeh
Unparticle cosmology gives an unconventional outlook on the dark sector of cosmology, increasingly challenging $Λ\mbox{CDM}$ by -tension. This model derives from a finite temp…
