Receipt: # 17078-1 ----- Attempting Submission 2 (Wed Jul 13 10:05:08 GMT 2022) ----- ----- Attempting Submission 3 (Tue Feb 14 11:49:20 GMT 2023) ----- A multi-wavelength view of interstellar dust Dust in the diffuse interstellar medium is a major contributor to the energy balance and chemistry in galaxies. Its properties are typically characterized in extinction against background sources, and have yielded a well-described interstellar extinction curve (IEC), that can be explained by several dust models. We propose to observe with HST/STIS 12 sightlines towards O and B stars selected in approved JWST program 2183, yielding a continuous spectrum over 0.11-28 micron with relatively uniform S/N. HST/STIS is currently the only instrument available that can provide spectroscopy to be effectively combined with JWST when targeting O and B stars. Analysis of the combined data set will result in a refining of the interstellar dust models, and further explore variations between sightlines. Several dust features in the IEC accessible with HST/STIS, most notably the 2175 A bump, but also the newly described intermediate scale structure features in the optical (Massa et al. 2020), will be compared to dust features in the infrared spectrum in order to further constrain the nature of their carriers. The overall shape of the IEC over the UV/optical/infrared wavelength range will further constrain the composition of the interstellar dust, in particular the balance between silicate and carbonaceous dust components, as well as the grain size distribution in the ISM. We will observe 12 stars using the STIS spectrograph to study the dust properties along these 12 sightlines. From the resulting spectra we will derive the particle size distribution and the chemical composition of the dust. In particular, we will study the intermediate scale structure (ISS) bands at 4370, 4870 and 6300 angstrom (for all sources) and the 2175 angstrom feature for stars that are bright enough near this wavelength. Through Phase 1 simulations we have seen that SNR~1 is sufficient to measure the full depth of the 2175 angstrom feature seen in G230L. The G140L data will help establishing the baseline continuum. Shallow but broad dust absorption features are expected in the spectral range (~4000A-7000A) of the CCD. They require a good handling of low order instrumental features. CCD + MAMA observations are split across different visits to improve schedulability. Following the HST program 13760 and Fitzpatrick 2019 (paper VII) we use the 52x2 slit for the most accurate spectrophotometric performance. The E1/E2 pseudoslits are not used as the targets are bright in the first order gratings for the CCD. CCD observations use a pattern with 4 positions with half pixel offsets (10.5 px) to prevent both hot pixels and improve spatial resolution (and remove low order ripple due to aliasing). G750L observations have a CCDFLAT at the end of their orbit for fringe correction. MAMA observations use a pattern with 2 positions with integer pixel offsets (15 px) to prevent hot pixels. The improvement spatial resolution is already given by MAMA's readout. All targets are OB stars with strong reddening. They have Av values ranging between 4-8 according to photometric fits, using photometry data (B-V,H-K) of Gaia and 2MASS, irsa dust maps and hydrogen column density maps, 2D HI4PI. BOT reports targets 2,3,4 as safe for MAMA according to GALEX data. But BOT reports potential problems with some stars (targets 5,6,7,8) in combination with MAMA because GALEX data is missing and GSC data is used to extrapolate with no reddening. The ETC calculations with the SIMBAD U or B magnitudes show us that the limits are not exceeded when normalized to the observed magnitudes in the UV and using our fitted Av values. We performed an additional check on the brightest star in our target list CPD-59 5831 (target 3, which is safe according to GALEX). The lowest allowed E(B-V) value would be 0.9 assuming an O5V star in order to avoid exceeding the limits on the total count rate. We are well above this value with an E(B-V)=1.5+-0.03. In addition the IRSA dust maps for this region based on Schlafly & Finkbeiner 2011 report an average E(B-V) of 2.15 +-0.06. We have assembled a team of experts with vast experience and broad knowledge of interstellar dust, i.e. theoretical models of dust, observations and modelling (over a broad wavelength range), and laboratory measurements. Together we are able to investigate the dust in the diffuse interstellar medium in all its aspects and details. The team has been set up with complementary sub-groups addressing the silicate and carbonaceous components of the diffuse ISM and especially in the UV, along with specialist sub-groups to identify appropriate targets, develop modelling tools for interpretation of the observations, and HST and JWST experts.
