Electric current
Radiant heat is electromagnetic radiation. Thermal heat is the micro kinetic energy of the component atoms or molecules of a material substance. The "or" of the question can not be answered because there is no "or" involved.
Radiation is the transfer of energy by electromagnetic waves.
Thermal energy can be transferred through electromagnetic waves by radiation. This process does not require a medium and can occur in a vacuum. Heat is transferred when an object emits infrared radiation, which carries thermal energy from the warmer object to a cooler one.
Infrared radiation is the electromagnetic wave that transfers thermal energy from a fireplace to warm objects or people in its vicinity. It is not visible to the human eye but can be felt as heat.
Yes, electromagnetic waves transfer energy through oscillating electric and magnetic fields. These waves can travel through a vacuum and carry energy from one place to another. The amount of energy carried by an electromagnetic wave is proportional to its frequency.

Thermal energy is an electromagnetic wave, as light is. Light (and other electromagnetic waves) travel best through empty space. They consist of an electric and magnetic field, that propagates as a wave.
Electromagnetic waves transfer energy.

Electromagnetic wave, yes.
yes
Now, this question has two answers. To give rise to, and to absorb, thermal radiation, matter is needed. Energy in the form of gravitational or electromagnetic fields neither emits nor absorbs thermal radiation. However, thermal radiation, an electromagnetic wave, does not need matter to transverse space.
