Searching optimal scales for reconstructing cosmological initial conditions using convolutional neural networks
Koichiro Nakashima, Kiyotomo Ichiki, Atsushi J. Nishizawa +1
Reconstructing the initial density field of the Universe from the late-time matter distribution is a nontrivial task with implications for understanding structure formation in cosm…
Survival of Gas in Subhalos and Its Impact on the 21 cm Forest Signals: Insights from Hydrodynamic Simulations
Genki Naruse, Kenji Hasegawa, Kenji Kadota +2
Understanding the survival of gas within subhalos under various astrophysical processes is crucial for elucidating cosmic structure formation and evolution. We study the resilience…
Impacts of pre-initial conditions on anisotropic separate universe simulations: a boosted tidal response in the epoch of reionization
Shogo Masaki, Takahiro Nishimichi, Masahiro Takada
To generate initial conditions for cosmological -body simulations, one needs to prepare a uniform distribution of simulation particles, so-called the pre-initial condition (pre-…
Anisotropic separate universe simulations
Shogo Masaki, Takahiro Nishimichi, Masahiro Takada
The long-wavelength coherent overdensity and tidal force, which are not direct observables for a finite-volume survey, affect time evolution of cosmic structure formation and there…
Constraints on Earth-mass primordial black holes from OGLE 5-year microlensing events
Hiroko Niikura, Masahiro Takada, Shuichiro Yokoyama +2
We constrain the abundance of primordial black holes (PBH) using 2622 microlensing events obtained from 5-years observations of stars in the Galactic bulge by the Optical Gravitati…
