Survey of Water and Ammonia in Nearby galaxies (SWAN): Resolved Ammonia Thermometry, and Water and Methanol Masers in IC 342, NGC 6946 and NGC 2146
Mark Gorski, Jürgen Ott, Richard Rand +3
The Survey of Water and Ammonia in Nearby galaxies (SWAN) studies atomic and molecular species across the nuclei of four star forming galaxies: NGC\,253, IC\,342, NGC\,6946, and NG…
Limiting the Oscillations in Queues with Delayed Information Through a Novel Type of Delay Announcement
Sophia Novitzky, Jamol Pender, Richard Rand +1
Many service systems use technology to notify customers about their expected waiting times or queue lengths via delay announcements. However, in many cases, either the information…
The Westerbork Hydrogen Accretion in Local Galaxies (HALOGAS) Survey I. Survey Description and Pilot Observations
George Heald, Gyula Jozsa, Paolo Serra +7
We introduce a new, very deep neutral hydrogen (HI) survey being performed with the Westerbork Synthesis Radio Telescope (WSRT). The Westerbork Hydrogen Accretion in LOcal GAlaxieS…
CHANG-ES XVII: H-alpha Imaging of Nearby Edge-on Galaxies, New SFRs, and an Extreme Star Formation Region -- Data Release 2
Carlos J. Vargas, Rene Walterbos, Richard Rand +5
We present new narrow-band H-alpha imaging for 24 nearby edge-on galaxies in the CHANG-ES survey. We use the images in conjunction with WISE 22 micron imaging of the sample to esti…
Breaking the Symmetry in Queues with Delayed Information
Philip Doldo, Jamol Pender, Richard Rand
Giving customers queue length information about a service system has the potential to influence the decision of a customer to join a queue. Thus, it is imperative for managers of q…
Dynamics of Two Coupled van der Pol Oscillators with Delay Coupling Revisited
Mark Gluzman, Richard Rand
The problem of two van der Pol oscillators coupled by velocity delay terms was studied by Wirkus and Rand in 2002. The small-epsilon analysis resulted in a slow flow which containe…
