New Photometric and Kinematic Evidence for a Bar in NGC 2841

We report finding a bar in the massive spiral NGC 2841 from both photometric and kinematic modeling. Visually, this galaxy possesses flocculent spiral structure and an inner hole devoid of dust and neutral HI gas, but no obvious indication of a stellar bar. While there has been some previous speculation of a bar based off of isophotal photometry of NGC 2841, there has been no recent follow-up work or confirmation, and this galaxy is considered unbarred in modern catalogues and surveys. We use the DiskFit code to model broadband B, V, R, I photometry from the ARCTIC imager on the APO 3.5m telescope and Halpha velocity field kinematics from data taken with the SparsePak IFU on the 3.5m WIYN telescope at KPNO. In both cases, we find that including a bar that is nearly aligned with the major axis of the galaxy significantly improves the fit of the DiskFit models. Here we report our results and discuss them in the context of previous work.
