Resumen
El transitorio de alta energía Sw 1644+57 sugiere un evento de acreción repentina en un agujero negro masivo (MBH). Este evento produjo un blazar temporal de menor escala con una salida relativista.
Área de la Ciencia:
- La astrofísica es la astrofísica.
- Astrofísica de altas energías de alta energía.
- Acreción de agujero negro.
Sus antecedentes:
- La mayoría de los agujeros negros masivos (MBH) están inactivos, careciendo de una emisión luminosa significativa.
- Las llamaradas de disrupción de marea (TDF, por sus siglas en inglés) ocurren cuando las estrellas son desgarradas gravitacionalmente cerca de MBHs.
- El transitorio Sw 1644+57 mostró inicialmente características atípicas para un TDF.
Objetivo del estudio:
- Para investigar la naturaleza del transitorio de alta energía Sw 1644+57.
- Para determinar si Sw 1644+57 resultó de un evento de acreción repentina en un MBH.
- Para caracterizar los procesos físicos y el flujo de salida asociados con Sw 1644+57.
Principales métodos:
- Análisis de los datos de observación del transitorio de alta energía Sw 1644+57.
- Análisis espectroscópico para identificar los procesos de emisión.
- Modelado de fenómenos de acreción y flujo de salida.
Principales resultados:
- Las observaciones sugieren que Sw 1644+57 resultó de una súbita acreción en un MBH (10^6 a 10^7 masas solares).
- La evidencia indica un flujo de salida ligeramente relativista y una colimación de chorros.
- El espectro observado se caracteriza por procesos de sincrotrón e inverso de Compton.
Conclusiones:
- Sw 1644+57 puede interpretarse como un blazar temporal de menor escala.
- Este evento proporciona información sobre los procesos de acreción en los MBH y las salidas asociadas.

01:10Detection of Black Holes
Although black holes were theoretically postulated in the 1920s, they remained outside the domain of observational astronomy until the 1970s.
Their closest cousins are neutron stars, which are composed almost entirely of neutrons packed against each other, making them extremely dense. A neutron star has the same mass as the Sun but its diameter is only a few kilometers. Therefore, the escape velocity from their surface is close to the speed of light.

01:21Schwarzschild Radius and Event Horizon
No object with a finite mass can travel faster than the speed of light in a vacuum. This fact has an interesting consequence in the domain of extremely high gravitational fields.
The minimum speed required to launch a projectile from the surface of an object to which it is gravitationally bound so that it eventually escapes the object’s gravitational field is called the escape velocity. The escape velocity is independent of the mass of the object. Merging the idea of escape velocity with the...

01:29Potential Due to a Polarized Object
A neutral atom consists of a positively charged nucleus surrounded by a negatively charged electron cloud. When placed in an external electric field, the external electric force pulls the electrons and nucleus apart, opposite to the intrinsic attraction between the nucleus and the electrons. The opposing forces balance each other with a slight shift between the center of masses of the nucleus and the electron cloud, resulting in a polarized atom. On the other hand, a few molecules, like water,...
01:14Gravitation Between Spherically Symmetric Masses
The gravitational potential energy between two spherically symmetric bodies can be calculated from the masses and the distance between the bodies, assuming that the center of mass is concentrated at the respective centers of the bodies.
01:03Rocket Propulsion in Gravitational Field - II
A rocket's velocity in the presence of a gravitational field is decreased by the amount of force exerted by Earth's gravitational field, which opposes the motion of the rocket. If we consider thrust, that is, the force exerted on a rocket by the exhaust gases, then a rocket's thrust is greater in outer space than in the atmosphere or on a launch pad. In fact, gases are easier to expel in a vacuum.
A rocket's acceleration depends on three major factors, consistent with the equation for the...

01:20Rocket Propulsion in Gravitational Field - I
Rockets range in size from small fireworks that ordinary people use to the enormous Saturn V that once propelled massive payloads toward the Moon. The propulsion of all rockets, jet engines, deflating balloons, and even squids and octopuses are explained by the same physical principle: Newton's third law of motion. The matter is forcefully ejected from a system, producing an equal and opposite reaction on what remains.
The motion of a rocket in space changes its velocity (and hence its...
