[7] It was observed in the infrared using the Cerro Tololo Inter-American Observatory (CTIO) 4m telescope, as part of a study of regions of intense star formation.

[1][4][9] The first published detection of Lyman continuum photons from T1247 was made in 2013 by Leitet et al. using data from the Far Ultraviolet Spectroscopic Explorer (FUSE).

However, to date it is unclear which physical mechanisms effectively produce large amounts of LyC photons, such that the reionization of the universe could be powered.

For that reason local galaxies such as TOL1247 are studied in detail, in order to understand physical processes that produce escaping LyC photons.

In TOL1247 it was found that bulk of the LyC photons emerges from two massive stellar clusters located in the central region of the galaxy.
