A systematic study of silicate absorption features in heavily obscured AGNs observed by Spitzer/IRS
T. Tsuchikawa, H. Kaneda, S. Oyabu +4
Heavily obscured active galactic nuclei (AGNs) are known to show deep silicate absorption features in the mid-infrared (IR) wavelength range of 10--20~m. The detailed profiles o…
Near- to mid-infrared spectroscopy of the heavily obscured AGN LEDA 1712304 with AKARI/IRC
T. Tsuchikawa, H. Kaneda, S. Oyabu +5
Context. Although heavily obscured active galactic nuclei (AGNs) have been found by many observational studies, the properties of the surrounding dust are poorly understood. Using…
Rotating and infalling motion around the high-mass young stellar object Cepheus A-HW2 observed with the methanol maser at 6.7 GHz
K. Sugiyama, K. Fujisawa, A. Doi +9
We have measured the internal proper motions of the 6.7 GHz methanol masers associated with Cepheus A (Cep A) HW2 using Very Long Baseline Interferometery (VLBI) observations. We c…
Size of the Vela Pulsar's Emission Region at 18 cm Wavelength
C. R. Gwinn, M. D. Johnson, J. E. Reynolds +12
We present measurements of the linear diameter of the emission region of the Vela pulsar at observing wavelength lambda=18 cm. We infer the diameter as a function of pulse phase fr…
Noise in the Cross-Power Spectrum of the Vela Pulsar
C. R. Gwinn, M. D. Johnson, J. E. Reynolds +12
We compare the noise in interferometric measurements of the Vela pulsar from ground- and space-based antennas with theoretical predictions. The noise depends on both the flux densi…
Measuring the brightness temperature distribution of extragalactic radio sources with space VLBI
S. J. Tingay
We have used VSOP space very long baseline interferometry observations to measure the brightness temperature distribution of a well-defined sub-set of the Pearson-Readhead sample o…
Measuring the Size of the Vela Pulsar's Radio Emission Region
C. R. Gwinn, J. E. Reynolds, D. L. Jauncey +9
We describe measurements of the size of the Vela pulsar via scintillation, using both fits to the distribution of intensity and measurements of the modulation index. We briefly dis…
