ViCTORIA project: MeerKAT HI observations of the ram pressure stripped galaxy NGC 4523
A. Boselli, P. Serra, F. de Gasperin +22
We present the first results of a 21 cm HI line pilot observation carried out with MeerKAT in preparation for the ViCTORIA project, an untargeted survey of the Virgo galaxy cluster…
Radio continuum tails in ram pressure-stripped spiral galaxies: experimenting with a semi-empirical model in Abell 2255
A. Ignesti, B. Vulcani, A. Botteon +7
Wide-field radio continuum observations of galaxy clusters are revealing an increasing number of spiral galaxies hosting tens of kpc-long radio tails produced by the nonthermal int…
Gas accretion and Ram Pressure Stripping of Haloes in Void Walls
B. B. Thompson, R. Smith, K. Kraljic
We conduct hydrodynamical cosmological zoom simulations of fourteen voids to study the ability of haloes to accrete gas at different locations throughout the voids at z = 0. Measur…
Initial Conditions for Star Formation: A Physical Description of the Filamentary ISM
A. Hacar, S Clark, F. Heitsch +4
The interstellar medium contains filamentary structure over a wide range of scales. Understanding the role of this structure, both as a conduit of gas across the scales and a diagn…
Abundance ratios and IMF slope in the dwarf elliptical galaxy NGC~1396 with MUSE
J. J. Mentz, F La Barbera, R. F. Peletier +16
Deep observations of the dwarf elliptical (dE) galaxy NGC 1396 (M, Mass M), located in the Fornax cluster, have been performed with the VLT/…
A Comprehensive X-ray Spectral Analysis of the Seyfert 1.5 NGC 3227
A. Markowitz, J. N. Reeves, I. M. George +5
We present results of a 100 ks XMM observation of the Seyfert 1.5 NGC 3227. Our best-fit broadband model to the pn spectrum consists of a moderately flat (photon index 1.57) hard X…
Comparison of 3.6 - 8.0 Micron Spitzer/IRAC Galactic Center Survey Point Sources with Chandra X-Ray Point Sources in the Central 40x40 Parsecs
R. G. Arendt, D. Y. Gezari, S. R. Stolovy +8
We have studied the correlation between 2357 Chandra X-ray point sources in a 40 x 40 parsec field and ~20,000 infrared sources we observed in the corresponding subset of our 2 x 1…
X-ray and optical variability of Seyfert 1 galaxies as observed with XMM-Newton
R. Smith, S. Vaughan
We have examined simultaneous X-ray and optical light curves of a sample of eight nearby Seyfert 1 galaxies observed using the EPIC X-ray cameras and Optical Monitor on board XMM.…
The Rapid Decay of the Optical Emission from GRB 980326 and its Possible Implications
Paul J. Groot, Titus J. Galama, Paul M. Vreeswijk
We report the discovery of the optical counterpart to GRB 980326. Its rapid optical decay can be characterized by a power law with exponent -2.10 +/- 0.13 and a constant underlying…
