英文摘要We measure the distance to the supernova remnant G15.4+0.1 which is likely associated with TeV source HESS J1818-154. We build the neutral hydrogen (HI) absorption and (CO)-C-13 spectra for supernova remnant G15.4+0.1 by employing data from the Southern Galactic Plane Survey (SGPS) and the HI/OH/Recombination line survey (THOR). The maximum absorption velocity of about 140 km s(-1) constrains the lower limit of its distance to about 8.0 kpc. Further, the fact that the HI emission feature at about 95 km s(-1) seems to have no corresponding absorption suggests that G15.4+0.1 likely has an upper limit for distance of about 10.5 kpc. The (CO)-C-13 spectrum for the remnant supports our measurement. The new distance provides revised parameters on its associated pulsar wind nebula and TeV source.
