Limits on Magnetized Quark-Nugget Dark Matter from Episodic Natural Events

A quark nugget is a hypothetical dark-matter candidate composed of approximately equal numbers up, down, and strange quarks. Most models nuggets do not include effects their intrinsic magnetic field. However, Tatsumi used mathematically tractable approximation the Standard Model Particle Physics found that cores magnetar pulsars may be in ferromagnetic liquid state with surface field Bo between $10^{ 11}$ T 13}$ T. We have applied result to quark-nugget dark matter. Previous work addressed formation aggregation magnetized (MQNs) into broad magnetically stabilized mass distribution before they could decay interaction normal matter through magnetopause, losing translational velocity while gaining rotational radiating electromagnetic energy. The two orders magnitude uncertainty estimate for precludes practical design systematic experiments detect MQNs predicted In this paper, we examine episodic events consistent unique signature MQNs. If are indeed caused by MQNs, constrain most likely values $1.65 x 10^{ 12}$ $+/-$ $21\%$ support definitive tests MQN hypothesis.
