Modelling the 6.7 GHz Methanol Flaring in G358.93-0.03 Using the Maxwell-Bloch Framework
Ningyan Fang, Toktam Rashidi, Yoshinori Yonekura +4
We model selected 6.7 GHz methanol flare profiles in G358.93-0.03 using the one-dimensional Maxwell-Bloch framework. The 2019 non-periodic flare, associated with an accretion burst…

Impact of the axion-like self-interactions in gravitational atoms for LISA
Samuel Gómez Gómez, Xisco Jimenez Forteza, Carlos Palenzuela Luque
Ultralight bosons with self-interactions, such as axion-like particles, can form astrophysical Bose--Einstein condensates around stars or compact objects, often referred to as grav…

Shaping black hole resonances I. Black hole ringdown as a spectral filtering process
Alejandro Svyatkovskyy Kholyavka, Jose Antonio León Vega, Samuel Gómez Gómez +2
The ringdown of a perturbed black hole (BH) can be described as a superposition of quasinormal modes (QNMs), whose frequencies are determined by the spacetime geometry while their…
