A Search for Extraplanar Dust in Nearby Edge-On Spirals
We present high resolution (0. ′′6 to ∼ 1. ′′0) BV images of 12 edge-on spiral galaxies observed with the WIYN 3.5-m telescope. These images were obtained to search for extraplanar (|z| > 0.4 kpc) absorbing dust structures similar to those previously found in NGC 891 (Howk & Savage 1997). Many of these galaxies have been previously searched for diffuse ionized gas at high z. Our imaged galaxies...
متن کاملClues to Nuclear Star Cluster Formation from Edge-on Spirals
We find 9 nuclear cluster candidates in a sample of 14 edge-on, late-type galaxies observed with HST/ACS. These clusters have magnitudes (MI ∼ −11) and sizes (reff ∼ 3 pc) similar to those found in previous studies of face-on, late-type spirals and dE galaxies. However, three of the nuclear clusters are significantly flattened and show evidence for multiple, coincident structural components. Th...

متن کاملDeep surface photometry of edge - on spirals in Abell galaxy clusters : constraining environmental effects
Context. There is a clear scarcity of structural parameters for stellar thick discs, especially for spiral galaxies located in high-density regions, such as galaxy clusters and compact groups. Aims. We have modelled the thin and thick discs of 4 edge-on spirals located in Abell clusters: NGC 705, ESO243G49, ESO187G19, LCSBS0496P. Deep I band images of NGC 705 were taken from the HST archive, wh...
متن کاملVisualizing Time-Series on Spirals
In this paper, we present a new approach for the visualization of time-series data based on spirals. Different to classical bar charts and line graphs, the spiral is suited to visualize large data sets and supports much better the identification of periodic structures in the data. Moreover, it supports both the visualization of nominal and quantitative data based on a similar visualization meta...
