Hubble’s Tuning Fork: A Classification Diagram for Galaxies: Match The Galaxy Classification On Hubble’s Tuning Fork.
The Hubble Tuning Fork is a diagram that classifies galaxies based on their morphology. It is a valuable tool for understanding galaxy evolution, as it provides insights into the different pathways galaxies can take over time.
Matching Galaxies to the Tuning Fork
To match observed galaxies to the different regions of the tuning fork, astronomers use criteria such as:
- Morphological characteristics (e.g., shape, size, surface brightness)
- Spectral properties (e.g., color, emission lines)
- Star formation rates
Matching galaxies to the tuning fork can be challenging due to the diversity of galaxy properties and the limitations of observational techniques.
Galaxy Properties and Tuning Fork Position, Match the galaxy classification on hubble’s tuning fork.
The position of a galaxy on the tuning fork is related to its properties, including:
- Morphology: Elliptical galaxies are located at one end of the tuning fork, while spiral galaxies are at the other end.
- Color: Blue galaxies are located at the end of the tuning fork with higher star formation rates, while red galaxies are at the end with lower star formation rates.
- Star formation rate: Galaxies with higher star formation rates are located at the end of the tuning fork with more irregular morphologies.
These properties can be used to infer the evolutionary history of galaxies.
Deviations from the Tuning Fork
Some galaxies deviate from the typical tuning fork pattern. These galaxies may have unusual morphologies, colors, or star formation rates.
- Starburst galaxies: These galaxies have extremely high star formation rates and are located at the end of the tuning fork with the most irregular morphologies.
- Quasar galaxies: These galaxies are extremely luminous and have active galactic nuclei. They are located at the end of the tuning fork with the highest redshifts.
Implications for Galaxy Evolution
The tuning fork provides insights into the evolution of galaxies. It suggests that galaxies can evolve from one type to another over time.
- Elliptical galaxies are thought to form from the merger of smaller galaxies.
- Spiral galaxies are thought to form from the accretion of gas and the subsequent formation of stars.
- Galaxies can transition from one type to another through processes such as starbursts and mergers.
