The Delta-isobar masquerade: intrahadronic phase transitions and their quark-mimicking signatures in neutron stars

Martin O. Canullan-Pascual, Germán Lugones, Ignacio F. Ranea-Sandoval +1

We investigate the conditions under which $\Delta (1232)$ isobars trigger a first-order phase transition within purely hadronic neutron-star matter, using the SW4L relativistic mean-fiel…
