Systematic study of the morphology and length of slow stable hybrid star branches

Mauro Mariani, Milva G. Orsaria, Germán Lugones +1

We introduce and systematically study the length of the slow stable hybrid star branch as a quantitative measure of the extended stability region that arises in hybrid neutron star…

Sensitivities of Black Hole Images from GRMHD Simulations

Pedro Naethe Motta, Mário Raia Neto, Cora Prather +1

The advent of high-fidelity imaging of supermassive black holes calls for efficient and robust data-analysis methods. In this work, we use , a differentiable, $\te…

Search for ultra-high energy neutrons from Galactic sources with the Pierre Auger Observatory

The Pierre Auger Collaboration, A. Abdul Halim, P. Abreu +357

Deflections in the propagation of charged ultra-high-energy cosmic rays (UHECRs) caused by magnetic fields make the identification of their sources challenging. On the other hand,…

The Radius of PSR J0437-4715 from NICER Data

M. C. Miller, A. J. Dittmann, I. M. Holt +12

Neutron star Interior Composition Explorer (NICER) data have been used to estimate the masses and radii of the rotation-powered millisecond pulsars PSR J00300451, PSR J074066…

Towards a unified hadron-quark equation of state for neutron stars within the relativistic mean-field model

Marcos O. Celi, Mauro Mariani, Milva G. Orsaria +2

The equation of state of dense matter remains a central challenge in astrophysics and high-energy physics, particularly at supra-nuclear densities where exotic degrees of freedom l…

Self-bound quark stars with a first-order two-to-three flavor phase transition

G. Teruya, G. Lugones, A. G. Grunfeld

We investigate self-bound quark stars in a flavor-dependent quark-mass density-dependent model with an excluded-volume correction. We chart the parameter space at zero pressure to…
