GW190814's Mystery Object Explained: A New Compact Object Regime in the CCEGA Framework

Key Points

• The aim is to describe the phase diagram of compact objects in the CCEGA framework and identify new regimes.
• Developed a complete phase diagram for compact objects in CCEGA.
• Identified critical masses, including M_max and M_crit.
• Analyzed properties of ultracompact horizonless objects not found in general relativity.
• Established two critical masses: M_max at 2.330 M☉ and M_crit at 9.20 M☉.
• Discovered an intermediate regime for objects between 2.33 M☉ and 9.20 M☉.
• Positioned GW190814's secondary object (2.59 M☉) within this newly identified regime.
