Resumen:

ÉBANO will be a new instrument for the 84-cm telescope in the Observatorio Astronómico Nacional in Sierra de San Pedro Mártir (Baja California Norte, Mexico) that will do integral field spectroscopy over two spectral ranges of 30 nm in wavelength in an unusually large field of view of 6.5×6.5 arcsec.The technique used by ÉBANO allows a wavelength scan over a wide spectral range by tilting a narrow-band filter thus changing the central wavelength of the transmission curve.We plan to begin observations with a complete cartography of the Andromeda galaxy (M31) with a mosaic of over 250 images, a region never fully explored with spatially resolved spectroscopy.Using two different filters we will sample the spectral range that covers the lines of NII, Ha, HeI and SII, and the range that covers OIII and Hß, which gives ÉBANO a huge scientific potential. © 2024 SPIE.
