Probing the Central Regions of Nearby Compact Elliptical Galaxies
T. J. Davidge, T. L. Beck, P. J. McGregor
K-band spectroscopic observations recorded with NIFS+ALTAIR on Gemini North are used to probe the central arcsec of the compact elliptical galaxies NGC 4486B, NGC 5846A, and M32. T…
The Ionizing Stars of the Galactic Ultra-Compact HII Region G45.45+0.06
Robert D. Blum, Peter J. McGregor
Using the NIFS near-infrared integral-field spectrograph behind the facility adaptive optics module, ALTAIR, on Gemini North, we have identified several massive O-type stars that a…
Mapping of the molecular gas inflow towards the Seyfert nucleus of NGC4051 using Gemini NIFS
Rogemar A. Riffel, Thaisa Storchi-Bergmann, Claudia Winge +3
We present two-dimensional (2D) stellar and gaseous kinematics of the inner ~130x180 pc^2 of the Narrow Line Seyfert 1 galaxy NGC4051 at a sampling of 4.5 pc, from near-infrared K-…
Spatially Resolved Molecular Hydrogen Emission in the Inner 200AU Environments of Classical T Tauri Stars
Tracy L. Beck, Peter J. McGregor, Michihiro Takami +1
We present 2.0-2.4micron integral field spectroscopy at adaptive optics spatial resolution (~0.''1) obtained with the Near-infrared Integral Field Spectrograph (NIFS) at Gemini Nor…
A Micro Molecular Bipolar Outflow From HL Tau
Michihiro Takami, Tracy L. Beck, Tae-Soo Pyo +2
We present detailed geometry and kinematics of the inner outflow toward HL Tau observed using Near Infrared Integral Field Spectograph (NIFS) at the Gemini-North 8-m Observatory. W…
Radio-Excess IRAS Galaxies: IV. Optical Spectroscopy
Catherine L. Buchanan, Peter J. McGregor, Geoffrey V. Bicknell +1
This is the fourth in our series of papers investigating radio-excess galaxies, which have radio emission associated with an active nucleus but which do not fit into the traditiona…
