Hi intensity mapping
WebMay 1, 2024 · The HI intensity mapping technique consists of making maps of the brightness temperature of the sky at different frequencies. Since no other emission lines appear at these radio frequencies, there is a unique relation between observed frequency and redshift, ( 1 + z ) ν = ν HI = c ∕ λ HI , with λ HI = 21 cm the rest-frame wavelength of ... WebHigh-intensity focused ultrasound (HIFU) is a minimally invasive medical procedure that uses ultrasound waves to treat certain conditions, such as tumors, uterine fibroids and tremor. The very high-intensity and highly focused sound waves interact with targeted tissues in your body to modify or destroy them. Appointments & Access.
