Numerical implementation of flat FLRW models of cosmic expansion with Planck 2018 cosmological parameters
Julio Carlos Bertua Marasca, Homer Davila Gutierrez, Oswaldo Alberto Martinez Osorio +2
We present an explicit numerical implementation of the Friedmann equations to model the expansion of the Universe in spatially flat, homogeneous and isotropic Friedmann-Lemaitre-Ro…
Solar Cycle 25 Dynamics from Observational and Statistical Parameters: Characterization of the Maximum Phase and Rotational Behaviour
Homer Dávila Gutiérrez
We present a comprehensive analysis of Solar Cycle 25 aimed at precisely constraining the interval of its activity maximum using multiple observational parameters: sunspot number (…
From M100 to NGC 7331: A Multiband Study and Physical Parameters in Nearby Galaxies
Julio C. Bertua Marasca, Homer Dávila Gutiérrez, Víctor Huamán Ticona +2
We study five nearby galaxies (M100/NGC 4321, NGC 1300, M 74, M 60, and NGC 7331) by combining multiband imaging (optical, UV, NIR, and X-rays) with simple photometric measurements…
Seasonal and Diurnal Variability of Atmospheric Pressure in Jezero Crater, Mars, from MEDA Measurements on the Perseverance Rover
Julio Carlos Bertua Marasca, Homer Davila Gutierrez, Josue Ismael Mosquera Hadatty
We present an analysis of atmospheric pressure variability inside Jezero Crater on Mars based on measurements from the MEDA meteorological station aboard NASA's Perseverance rover.…
