1999AJ....118..826I AN INFRARED DETERMINATION OF THE REDDENING AND DISTANCE TO DWINGELOO 1 VALENTIN D. IVANOV, ALMUDENA ALONSO-HERRERO, MARCIA J. RIEKE AND DON MCCARTHY Steward Observatory, University of Arizona, 933 North Cherry Avenue, Tucson, AZ 85721; vdivanov@as.arizona.edu, aalonso@as.arizona.edu, mrieke@as.arizona.edu, mccarthy@as.arizona.edu Received 1999 April 5; accepted 1999 May 6 ABSTRACT We present the first published infrared observations of the nearby, highly obscured galaxy Dwingeloo 1 (Dw 1), including deep H-band imaging covering a total of 4.9' x 4.9', together with J and K_s_ imaging of the central 2.5' x 2.5'. We used the small dispersion of the intrinsic infrared colors of spiral galaxies to determine an infrared H-band extinction of A_H_ = 0.47 +/- 0.11 mag toward Dw 1. Using infrared colors reduces the uncertainties in the reddening and distance by a factor of 3. The H-band magnitude, corrected for extinction, and the infrared Tully-Fisher relation are then used to estimate a distance modulus of (m -M)_0_ = 28.62 +/- 0.27 and, thus, a distance of d = 5.3_-0.6_^+0.7^ Mpc, which places Dw 1 at the far end of the IC 342/Maffei 1-2 group of galaxies. Our result is largely independent of the nature of the reddening law because we estimated both the reddening and the distance at the same wavelength range. Key words: galaxies: individual (Dwingeloo 1)-galaxies: distances and redshifts-galaxies: photometry-infrared radiation
