On the relative CNO underabundance in quasar absorption systems at arising from Population III enrichment and attenuation by intermediate-mass black holes and primordial baryon accretion
Murilo Macedo, Carlos Alexandre Wuensche, Oswaldo Duarte Miranda
This article uses an adapted version of the semi-analytical model of cosmic chemical enrichment developed by \citet{Corazza_2022} to reproduce the observed abundances of C, N, and…
The cosmological lithium problem
Oswaldo D. Miranda
The discrepancy between the predictions of primordial nucleosynthesis and the observed lithium abundance in Spite plateau stars has been attributed either to a challenge to the sta…
Optimal Detection Bands for Intermediate-Mass Black Hole Binaries: Prospects for LISA and AMIGO in General Relativity and Gravity
Marcelo M. Lapola, Oswaldo D. Miranda
We present a semi analytic forecast for the detection of intermediate mass black hole (IMBH) binaries with the space based detectors LISA (millihertz band) and AMIGO (deci hertz ba…
Potential contributions of Pop III and intermediate-mass Pop II stars to cosmic chemical enrichment
Lia C. Corazza, Oswaldo D. Miranda, Carlos A. Wuensche
We propose a semi-analytic model that is developed to understand the cosmological evolution of the mean metallicity in the Universe. In particular, we study the contributions of Po…
Magnetohydrodynamic waves excited by a coupling between gravitational waves and a strongly magnetized plasma in binaries of neutron stars
Adam S. Gontijo, Oswaldo D. Miranda
Coalescence of binary neutron stars (BNSs) is one of the sources of gravitational waves (GWs) able to be detected by ground-based interferometric detectors. The event GW170817 was…
Dark matter Annihilation in the Most Luminous and the Most Massive Ultracompact Dwarf Galaxies (UCD)
Elaine C. F. S. Fortes, Oswaldo D. Miranda, Floyd W. Stecker +1
In this paper, we explore the potential astrophysical signatures of dark matter (DM) annihilations in ultra-compact dwarf galaxies (UCDs) considering two of the richest known galax…
