A Bird's Eye View of Ocular Galaxies
Brinks, E.; Kaufman, M.; Elmegreen, D.M.; Struck, C.; Elmegreen, B.; Thomasson, M.; Klaric, M. (Astronomical Society of the Pacific, 2000)Ocular galaxies are systems undergoing an in-plane, near grazing, prograde encounter. In addition to the interaction causing the formation of two long, symmetrically opposite tidal tails, during a short period after ... -
CO Observations of the Interacting Galaxy Pair NGC 5394/95
Kaufman, M.; Sheth, K.; Struck, C.; Elmegreen, B.; Thomasson, M.; Elmegreen, D.M.; Brinks, E. (2002-02) -
Dust Spirals and Acoustic Noise in the Nucleus of the Galaxy NGC 2207
Elmegreen, B.; Elmegreen, D.M.; Brinks, E.; Yuan, C.; Kaufman, M.; Klaric, M.; Montenegro, L.; Struck, K.; Thomasson, M. (1998)Observations with the Hubble Space Telescope reveal an irregular network of dust spiral arms in the nuclear region of the interacting disk galaxy NGC 2207. The spirals extend from »50 to »300 pc in galactocentric radius, ... -
Effects of Grazing Encounters on Spiral Galaxies
Kaufman, M.; Struck, C.; Elmegreen, B.; Elmegreen, D.M.; Brinks, E.; Thomasson, M.; Klaric, M. (2001) -
Effects of Grazing Encounters on Spiral Galaxies
Kaufman, M.; Struck, C.; Elmegreen, B.; Elmegreen, D.M.; Brinks, E.; Thomasson, M.; Klaric, M. (Astronomical Society of the Pacific, 2001)We made radio, optical and CO observations of three pairs of spiral galaxies involved in recent, grazing encounters and compared our data with numerical simulations. The tidal structures seen in the galaxy undergoing a ... -
Gravitational bar and spiral arm torques from Ks-band observations and implications for the pattern speeds
Block, D.L.; Buta, R.J.; Knapen, J.; Elmegreen, D.M.; Elmegreen, B.; Puerari, I. (2004-07) -
The gravitational torque of bar in optically unbarred and barred galaxies
Block, D.L.; Puerari, I.; Knapen, J.; Elmegreen, B.; Buta, R.J.; Stedman, S.; Elmegreen, D.M. (2001-09) -
The Gravitational Torque of Bars
Puerari, I.; Block, D.L.; Knapen, J.; Elmegreen, B.; Buta, R.J.; Stedman, S.; Elmegreen, D.M. (Astronomical Society of the Pacific, 2002)We have determined the gravitational torque of a sample of 45 galaxies observed at K band with the 4.2m William Herschel Telescope. The results of this sample, combined with those for a sample of 30 galaxies previously ... -
The grazing encounter between IC 2163 and NGC 2207: pushing the limits of observational modelling
Struck, C.; Kaufman, M.; Brinks, E.; Thomasson, M.; Elmegreen, B.; Elmegreen, D.M. (2005) -
Herschel Spectroscopic Observations of Little Things Dwarf Galaxies
Cigan, P.; Young, L.; Cormier, D.; Lebouteiller, V.; Madden, S.; Hunter, D.; Brinks, E.; Elmegreen, B.; Schruba, A.; Heesen, V. (2016-01-04)We present far-infrared (FIR) spectral line observations of five galaxies from the Little Things sample: DDO 69, DDO 70, DDO 75, DDO 155, and WLM. While most studies of dwarfs focus on bright systems or starbursts due to ... -
HST observations of the interacting galaxies NGC 2207 and IC 2163
Elmegreen, B.; Kaufman, M.; Struck, C.; Elmegreen, D.M.; Brinks, E.; Thomasson, M.; Klaric, M.; Levay, Z.; Bond, H.E.; Christian, C.A.; English, J.; Frattare, L.; Hamilton, F.; Noll, K. (2000)Hubble Space Telescope (HST ) images of the galaxies NGC 2207 and IC 2163 show star formation and dust structures in a system that has experienced a recent grazing encounter. Tidal forces from NGC 2207 compressed and ... -
Hubble Space Telescope Observations of Dust and Star-forming Regions in the Ocular Galaxy IC 2163 and its Spiral Companion NGC 2207

Interaction Between NGC 5394 and NGC 5395
Kaufman, M.; Brinks, E.; Elmegreen, B.; Elmegreen, D.M.; Klaric, M.; Struck, C.; Thomasson, M.; Vogel, S. (Astronomical Society of the Pacific, 1999)The spiral galaxies NGC 5394/95 (at a distance of 47 Mpc) are involved in a recent, close, nonmerging encounter. The smaller galaxy, NGC 5394, has two long, fairly symmetric, open tidal arms (see Figure 1); in numerical ... -
