Measuring the temperature of quasars

In summary, the temperature of quasars can be measured using Maxwell's laws of distribution of velocities, but this will only give the electron temperature. The kinetic motion of atoms also produces Doppler shifts, which can be used to find the mean square velocity and calculate the temperature. More information on this equation can be found online.

Can anyone tell me whether it's possible to measure the temperatures of Quasers from phenomenon such as redshift etc??
As quasers travel with speed comparable to that of light,so does the concept of relativistic temperature come into effect?
Are there any research papers available on this?

Quasars don't travel with relativistic speeds but some of the particles emitted by jets from them do.
Some quasars are at very high cosmological red****s - a selection effect since they are the only things bright enough to see at high redshifts - but some such as the famous 3C273 are quite close.

u can measure the temperature of the quasar by using maxwells laws of distribution of velocities. but that measured temperature vil be the electron temperature.the kinetic motion of the atoms produce doppler shifts,dl=VL/C.WHERE dl IS THE SHIFTED WAVELENGTH and L is the original one. in the maxwells equation substitute dl in place of total no. of atoms (N). u vil get the mean square velocity from which u can find the temp. look for this equation on the net.
 

Related to Measuring the temperature of quasars

1. How do scientists measure the temperature of quasars?

Scientists use a method called spectroscopy to measure the temperature of quasars. This involves analyzing the light emitted by the quasar and determining the wavelength at which it is most intense. The temperature can then be calculated using this information.

2. What units are used to measure the temperature of quasars?

The temperature of quasars is typically measured in Kelvin (K), which is the standard unit for temperature in scientific measurements. This unit is based on the absolute temperature scale, where 0K represents absolute zero, or the point at which all molecular motion stops.

3. How hot are quasars compared to other celestial objects?

Quasars are some of the hottest objects in the universe, with temperatures reaching up to billions of degrees Kelvin. This is much hotter than stars, which typically have temperatures in the range of thousands to millions of degrees Kelvin.

4. Can the temperature of a quasar change over time?

Yes, the temperature of a quasar can change over time. This is due to the fact that quasars are powered by supermassive black holes, which can undergo periods of increased or decreased activity. This can cause fluctuations in the temperature of the quasar's emission.

5. Why is it important to measure the temperature of quasars?

Measuring the temperature of quasars is important because it can provide valuable information about the physical processes happening within these objects. By studying the temperature, scientists can gain insight into the composition and behavior of the matter and energy near the black hole that powers the quasar. This can also help us better understand the evolution of galaxies and the universe as a whole.
