A view of the horizontal velocity flows in the upper layers of the convection zone is presented. In order to produce the synoptic map, 120 sections of about 15 degrees square have been studied using a ring diagram analysis. The area analyzed extends 75 degrees in latitude and 360 degrees in longitude. The sections were individually tracked over

We have used a combination of optical absorption spectroscopy, 21 cm HI mapping, and millimetric CO mapping, to explore the fine structure of the ISM clouds within 200 pc of the sun. We find examples of molecular cores within cold atomic clouds, cold atomic clouds within warm ionized clouds, and warm ionized clouds without cold cores (using

Most of the information concerning the ionized gas and star kinematics in the central regions of galaxies is 1-Dimensional. This hampers the study of the velocity fields, specially for the ionized gas which in many cases exhibits a kinematics strongly decoupled from that of the stars. Here we present the velocity fields for the ionized gas and the

We present CO J = 1-> observations of the S0 galaxy NGC 404 obtained using the Nobeyama Millimeter Array. The spatial and velocity resolutions are 4' ' and 5 km s-1. The central part of the galaxy shows a highly concentrated rotationless source with properties typical of a Giant Molecular Association. This structure is compatible with either a
