Genesis Noir
A noir adventure spanning time and space.
You play as No Man, a watch peddler caught in a love triangle with other cosmic beings, Miss Mass and Golden Boy. When your affair turns into a bitter confrontation, you will witness a gunshot fired by a jealous god—otherwise known as The Big Bang. Jump into the expanding universe and search for a way to prevent or destroy creation and save your love.

Unraveling the early universe's equation of state and primordial black hole production with PTA, BBN, and CMB observations
Pulsar timing array (PTA) data releases showed strong evidence for a stochastic gravitational-wave background in the nanohertz band. When the signal is interpreted by a scenario of scalar-induced gravitational waves (SIGWs), we encounter overproduction of primordial black holes (PBHs). We wonder if varying the equation of state (EoS) of the early Universe can resolve this issue and thereby lead to a consistent interpretation of the PTA data. Analyzing a data combination of PTA, big-bang nucleos…

Improved Constraints on the Variation of the Weak Scale from Big Bang Nucleosynthesis
We present an improved calculation of the light element abundances in the framework of Big Bang nucleosynthesis as a function of the Higgs vacuum expectation value $v$. We compare the methods of our calculation to previous literature including the recently published work of Burns et al. [1]. The PDG result for the $^4$He abundance can be explained within $2σ$ by $-0.014 \leq δv / v \leq 0.026$, for deuterium we find the constraint $-0.005 \leq δv / v \leq -0.001$. These bounds are more strin…

#Shipping is a vital industry on the #GreatLakes, but even in modern times, it can be a dangerous industry. These ships are quite large and undergo stresses on these very big maritime systems. Many of the "Laker" fleet like the Michipicoten, are older, upgraded and repurposed vessels, but …

Observation of the Antimatter Hypernucleus $^4_{\barΛ}\overline{\hbox{H}}$
At the origin of the Universe, asymmetry between the amount of created matter and antimatter led to the matter-dominated Universe as we know today. The origins of this asymmetry remain not completely understood yet. High-energy nuclear collisions create conditions similar to the Universe microseconds after the Big Bang, with comparable amounts of matter and antimatter. Much of the created antimatter escapes the rapidly expanding fireball without annihilating, making such collisions an effective…

The impact of a primordial gravitational wave background on LISA resolvable sources
The existence of a primordial stochastic gravitational wave background (SGWB) is a common prediction in various models of the early Universe. Despite constraints at different frequency ranges and claims of detection in the nHz range by Pulsar Timing Arrays, the amplitude and spectral dependence of the SGWB in the mHz range remain largely unknown. Plausible models of early Universe Physics predict a wide range of SGWB amplitudes, from undetectable to exceeding the constraints from Big Bang Nucle…

Dark Matter from Evaporating Primordial Black Holes in the Early Universe
Primordial Black Holes (PBH) could dominate in the early universe and, evaporating before Big bang Nucleosynthesis, can provide new freeze in mechanism of dark matter (DM) production. The proposed scenario is considered for two possible mechanisms of PBH formation and the corresponding continuous PBH mass spectra so that the effect of non-single PBH mass spectrum is taken into account in the results of PBH evaporation, by which PBH dominance in the early universe ends. We specify the conditions…

Warm Hawking Relics From Primordial Black Hole Domination
We study the cosmological impact of warm, dark-sector relic particles produced as Hawking radiation in a primordial-black-hole-dominated universe before big bang nucleosynthesis. If those dark-sector particles are stable, they would survive to the present day as "Hawking relics" and modify the subsequent growth of cosmological structure. We show that such relics are produced with much larger momenta, but in smaller quantities than the familiar thermal relics considered in standard cosmology. Co…

Interacting light thermal-relic dark matter: self-consistent cosmological bounds
We analyze cosmic microwave background (CMB) data to constrain the mass and interaction strengths of thermally-produced dark matter (DM) in a self-consistent manner, simultaneously taking into account the cosmological effects of its mass and interactions. The presence of a light thermal-relic particle contributes non-negligibly to the radiation density during Big Bang Nucleosynthesis (BBN), altering the light-element yields, as well as the the effective number of relativistic particle species. …
