Abstract It is a long-standing puzzle why some early-type galaxies are radio-loud, while others are radio-quiet. We have been pursuing a program to address this issue by studying a sample of the 21 nearest powerful radio galaxies. We have obtained WFPC2 imaging in Cycle 6. In Cycle 8 we are obtaining STIS spectroscopy of the nuclear gas detected in these galaxies, to measure central black hole (BH) masses from the rotation rate of the emission-line gas, and to determine the nature and structure of the gas disks. From inspection of the HST/WFPC2 archive we have identified three galaxies with no radio jets and with Halpha+[NII] emission, which have dust disks similar to those commonly seen in our sample of radio-loud active galaxies. The difference in radio properties of these early- type galaxies may be related to differences in their BH mass and/or the absence of accretion of the present fuel. We propose to observe these galaxies with STIS. This will yield the first BH mass measurements from HST rotation measurements of emission-line gas disks in radio- quiet galaxies (previous studies such as for M87, M84, NGC4261, etc. were all for radio-loud systems). The results will advance our understanding of the nature of BHs in radio-loud and radio- quiet galaxies and its relation to the radio activity and the formation and physics of radio-jets. Only HST offers the high spatial resolution required for this study. ------------------------------------------------------------------------------------ 9163( 6) - 03/26/02 09:27 - [ 2] Observations Description ------------------------ HIGH-RESOLUTION SPECTROSCOPY. We will study the nuclear ionized gas kinematics using the Halpha+[NII] emission lines. These generally are the brightest optical emission lines in our galaxies, and are therefore the preferred choice for kinematical studies. We will observe the emission lines with STIS and the G750M grating at prime tilt lambda_cen=6768Angstrom. This covers the Halpha+[NII] lines for all galaxies, and includes the (redshifted) SII lines at 6716Angstrom and 6731Angstrom. We will observe NGC3078 with three parallel 0.2''-slit (52X0.2). NGC4526 and NGC6861 will be observed along 1 0.2''-slit (52X0.2). This choice represents a compromise between spatial resolution and coverage and signal-to-noise. WFPC2 NARROW-BAND IMAGING. We will obtain WFPC2 narrow-band exposures around Halpha+[NII] for NGC3078 and NGC6861. This is necessary for a proper dynamical interpretation. We will not image NGC4526. On- and off-band imaging with sufficient signal-to-noise is already available for NGC4526 in the HST archive.
