We present the first spatially resolved (~0.5 kpc) measurements of the molecular gas depletion time $tau_{depl}$ across the disk of the interacting spiral galaxy NGC,2276, a system with an asymmetric morphology in various SFR tracers. To estimate $tau_{depl}$, we use new NOEMA observations of the $^{12}$CO(1-0) emission tracing the bulk molecular gas reservoir in NGC 2276, and extinction-corrected H$alpha$ measurements obtained with the PMAS/PPaK integral field unit for robust estimates of the SFR. We find a systematic decrease in $tau_{depl}$ of 1-1.5 dex across the disk of NGC 2276, with a further, abrupt drop in $tau_{depl}$ of ~1 dex along the galaxys western edge. The global $tau_{depl}$ in NGC 2776 is $tau_{depl}=0.55$ Gyr, insistent with literature measurements for the nearby galaxy population. Such a large range in $tau_{depl}$ on sub-kpc scales has never previously been observed within an individual isolated or pre-merger system. When using a metallicity-dependent molecular gas conversion factor X$rm_{CO}$ the variation decreases by 0.5 dex. We attribute the variation in $tau_{depl}$ to the influence of galactic-scale tidal forces and ram pressure on NGC 2276s molecular interstellar medium (ISM). Our observations add to the growing body of numerical and observational evidence that galaxy-galaxy interactions significantly modify the molecular gas properties and star-forming activity within galactic disks throughout the interaction, and not just during the final merger phase.
We present a detailed clustering analysis of the young stellar population across the star-forming ring galaxy NGC 6503, based on the deep HST photometry obtained with the Legacy ExtraGalactic UV Survey (LEGUS). We apply a contour-based map analysis t
Star formation is a multi-scale process that requires tracing cloud formation and stellar feedback within the local (<kpc) and global galaxy environment. We present first results from two large observing programs on ALMA and VLT/MUSE, mapping cloud s
NGC 6872, hereafter the Condor, is a large spiral galaxy that is interacting with its closest companion, the S0 galaxy IC 4970. The extent of the Condor provides an opportunity for detailed investigation of the impact of the interaction on the curren
We present new $^{12}$CO(J=1-0) observations of the barred galaxy NGC 4303 using the Nobeyama 45m telescope (NRO45) and the Combined Array for Research in Millimeter-wave Astronomy (CARMA). The H$alpha$ images of barred spiral galaxies often show act
We present results for X-ray point sources in the Sc galaxy NGC 2276, obtained by analyzing Chandra data. The galaxy is known to be very active in many wavelengths, possibly due to gravitational interaction with the central elliptical of the group, N
