I tried to explain everything in the Observing Description, but if things are missing please ask. Note that I'll be out of email contact from July 19 - August 3. Resubmission August 11: Corrected coordinates of 1 target. This was SNL-0 in the proposal, but I accidentally changed it in the phase 2. It is now correct, and the same target as in the phase 1 proposal. The name was changed to ESO325-G004, as that is the more generally used name of the galaxy. 1412857741 ----- Attempting Submission 1 (Fri Jul 09 21:02:03 GMT 2021) ----- HST Phase II Proposal 16678 successfully submitted. Receipt: # 16678-1 ----- Attempting Submission 2 (Wed Aug 11 17:55:53 GMT 2021) ----- These calibration requirements are met - see Description. The question whether the stellar initial mass function (IMF) is universal or varies with galactic environment is one of the most vexing in all of astrophysics. In the past decade there has been a particular focus on the centers of massive early-type galaxies, as studies of gravity-sensitive absorption lines and kinematics have found evidence for an excess of low mass stars in these regions compared to the IMF of the Milky Way. We propose to test this hypothesis by measuring the average chromospheric activity of stars in the centers of 22 dust-free early-type galaxies spanning a wide range of masses, ages, abundances, and spectroscopically-derived IMFs. The chromospheres of M dwarfs are very active, as has been well-established in the context of the habitability of orbiting planets, and the average level of activity in a stellar population is a strong function of the prevalence of these stars. The dominant chromospheric emission line is Ly-alpha, which we can measure using the G130M grating of COS. If the IMF varies from galaxy to galaxy we expect to see a correlation between the strength of Ly-alpha and the strength of gravity-sensitive absorption features. The program uses the same instrumental setup as was used for observations of two early-type galaxies in Cycle 27, and an analysis of those observations shows that the measurements are feasible. The proposed spectra will have substantial long-term value beyond this primary aim. The Cycle 27 data appear to be the highest quality far-UV spectra of early-type galaxies ever taken, and the full sample will constitute a legacy spectroscopic dataset of HST that complements the many orbits of archival imaging of these galaxies. The goal of the program is to measure the Ly alpha emission line in 22 early-type galaxies. The program builds on our Cycle 27 program 15852, which obtained the same information for 2 early-type galaxies. We follow the same observing procedures as we used in 15852. The only difference is that 15852 obtained data with both G130M and G160M, in 2 + 2 orbits for each galaxy. Here we only obtain data in G130M, in 2 orbits. Each visit has the following structure: orbit 1: acquisition on offset star + blind offset + direct image on target + G130M exposure at 1291 Ang at FP-POS 3 orbit 2: G130M exposure at 1291 Ang at FP-POS 4 Brightness of the galaxies --------------------- The program aims to measure the faint Ly alpha line, but for the direct imaging and also for the expected continuum emission in the spectra it is important to have an approximate estimate of the continuum brightness. We calculated these from GALEX FUV and NUV data. The average brightness per square arcsec, which is needed in the ETC, is fairly constant in this diverse sample. As explained in phase 1, the reason is that intrinsically brighter galaxies tend to have shallower ("cored") surface brightness profiles, and intrinsically fainter galaxies tend to have steeper ("cuspy") profiles. As a result, we estimate that the average surface brightness within the central 0.4'' will be fairly constant across the sample, at ~22.5 mag in the NUV. This means that we are not anywhere near bright source limits, even if it is assumed that the light distribution within 0.4'' is a point source, and for simplicity we used 22.5 mag in the ETC calculation for both the 300s direct images and the spectroscopic observations. Brightness of the Ly alpha line ------------------------ This is estimated to be ~1e-15; this is discussed in the Phase 1 proposal (and measured for the two early-type galaxies of the Cycle 27 program). We are not near bright limits. Acquisition --------- The targets are too faint for a direct acquisition, and offset stars are used. The magnitudes of the stars were measured from GALEX NUV images. Exposure times were determined with the ETC. For most targets we used a S/N=30 criterion and MIRRORA. In some cases the stars are so faint that the S/N=30 criterion leads to very long exposure times for the individual acquisition frames (of 5 minutes or more). In these cases a S/N=20 criterion was used; this applies to: NGC1453, NGC3608, NGC4262, NGC4270, NGC4342, NGC4570, NGC4660. We note that for one galaxy, NGC4262, the offset star is so faint that 450s exposures are needed to get a S/N of 20. As two exposures are obtained in the acquisition process, this takes up a large chunk of the first orbit. In two other cases the offset star is too bright for MIRRORA as the count rate gets close to 50 cts/s: for NGC1404 and M85 MIRRORB was used instead. With these choices in all cases the maximum count rate is now ~5 cnts/s or less. The coordinates of the offset stars were obtained from Gaia and are extremely accurate. The offsets to the galaxies were determined from existing HST imaging in the cases where both the offset star and the galaxy are within a single existing HST observation. In cases where the offset star is not covered by existing HST data, 2MASS was used for the galaxy coordinates and the offset was determined from the difference between the Gaia coordinates of the star and the 2MASS coordinates of the galaxy. These are on the same system to ~0.2'' or better; we verified this. In all cases the proper motions of the stars are negligible. Direct images on target ------------------- After slewing to the science targets a short (300s) imaging exposure will be obtained to verify the location of the galaxy. As we do not know the exact brightness distribution of the galaxies on sub-arcsec scales it is difficult to estimate what, exactly, the S/N ratio will be. We assume that the average AB surface brightness within a 0.4'' aperture is about ~22.5 mag (see above). In 300s this gives a S/N ratio within this aperture of 20, sufficient to determine whether it is properly centered (and whether it is there!). If the light is more spread out, the S/N ratio will be lower, and if it is more peaked, the S/N ratio will be higher, but in either case we should be able to see both galaxies quite clearly if we are in the right place. Following section 6.1 in the Instrument Handbook, FLASH=YES was selected to track the drift of the OSMs. Again, for our Cycle 27 program this worked beautifully: we have images with a S/N ratio of ~1 per pixel and ~20 within 0.4'' of both galaxies, and these enabled us to verify that we were properly centered. Wavelength setting --------------- We use only a single setting for G130M (1291). With this setting Ly alpha is well covered and away from gaps. FP-POS settings ------------- In the context of COS2025 we can only use FP-POS 3 and FP-POS 4 with the G130M/1291 setting. We use position 3 for the first exposure and position 4 for the second. Conroy & van Dokkum have been working on the IMF in early-type galaxies since 2010, mostly using absorption line spectroscopy. Conroy is an expert in stellar populations, having developed a widely used stellar population synthesis code (FSPS). He made the model predictions shown in Fig. 3. van Dokkum is an expert in spectroscopy and HST data reduction. The ground-based spectroscopy of the parent sample was gathered by van Dokkum & Conroy over the past five years, and they determined the stellar population parameters. The Cycle 27 program that is the basis of this proposal was proposed and executed by the same authors; it was a pilot study to see if the present proposal would be feasible. The figures shown here are part of a paper on the Cycle 27 data that is in advanced stage of writing. Having developed the reduction and analysis procedures for these data, all procedures are in place for a rapid processing and publication of the data.
