description: Far ultraviolet emission lines are fundamental to interpret the ionized interstellar medium (ISM) properties of the first generation of galaxies that will be observed with the James Webb Space Telescope (JWST). The COS Legacy Archive Spectroscopic SurveY (CLASSY) HST-COS treasury program provided the first high-resolution spectral catalog of local high-z analogues to investigate their stellar and gas properties to improve the diagnostic power of UV lines. However comma  in order to fully understand the physical conditions that give rise to their excitation comma  we need to spatially tackle these diagnostics. This will allow us to trace their spatial distribution and to isolate the origin of the UV photons within these systems. Here we propose to obtain emission line images down to virgul10 pc resolution comma  using the high resolution imaging from ACS and STIS comma  of three nearby well-known low-metallicity starbursts selected from CLASSY. These sources are remarkably characterized by strong CIV1548 comma 1551 comma  HeII1640 comma  CORCHETE_OPENOIIICORCHETE_CLOSE1661 comma 6 and CORCHETE_OPENCIIICORCHETE_CLOSE1907 comma CIIICORCHETE_CLOSE1909 comma  and by different Ly-alpha profiles. The powerful combination of available optical integral field spectroscopy data comma  archival and new HST observations in concert with state-of-the-art models will allow us to investigate and interpret the morphology of the emission line diagnostics. Hence comma  not only we will be able to track the ionization source(s) of the gas and the ionization structure in our targets comma  but also test indirect tracers of leaking ionizing radiation (i.e. comma  Lyman continuum escape). This study will provide us with an extremely powerful toolkit comma  pivotal for understanding the ISM conditions of the earliest galaxies.

description: UNITE provides a unified way for delimiting, identifying, communicating, and working with DNA-based Species Hypotheses (SH). All fungal ITS sequences in the international nucleotide sequence databases are clustered to approximately the species level by applying a set of dynamic distance values (<0.5 - 3.0%). All species hypotheses are given a unique, stable name in the form of a DOI, and their taxonomic and ecological annotations are verified through distributed, web-based third-party annotation efforts. SHs are connected to a taxon name and its classification as far as possible (phylum, class, order, etc.) by taking into account identifications for all sequences in the SH. An automatically or manually designated sequence is chosen to represent each such SH. These sequences are released (https://unite.ut.ee/repository.php) for use by the scientific community in, for example, local sequence similarity searches and next-generation sequencing analysis pipelines.

description: A widely accepted tenant of galaxy formation theory is that red-and-dead galaxies maintain their quiescent status through the sustained impact of radio-mode feedback. Driven by an active galactic nucleus comma  this feedback is purported to heat gas in the galaxy.s surroundings to prevent the accretion and cooling of gas onto the galaxy. Moreover comma  radio-mode feedback drives gas outflows and may remove a substantive amount of gas from galaxies. While radio-mode feedback is now a nearly generic feature of numerical simulations of galaxy formation comma  the physical mechanisms that drive the interaction between radio jets-lobes and gas in galaxies are still poorly known. With this proposal comma  we will study a galaxy with bright radio jets (i.e. caught in the act) and therefore putatively exhibiting the radio-mode feedback that sustains its absence of star formation. Fortuitously comma  a UV luminous quasar lies background to this galaxy with its sightline intersecting the system at an impact parameter R virgul 4 kpc.  Existing optical spectra of the quasar shows likely CaII absorption associated with the foreground galaxy comma  i.e. cool and dense gas.  The proposed HST-COS observations will extend the analysis to a diverse set of diagnostics -- HI Lya comma  OI comma  SiII comma  SiIII comma  SiIV comma  CII comma  CIV -- to assess the metallicity comma  kinematics comma  and multi-phase nature of gas in the galaxy.  These data will provide direct insight into the process of radio-mode feedback and offer tests for current and future models.

description: The purpose of this program is to monitor charge traps in the ACS-WFC CCDs at the lowest charge level and update the pixel-based CTE model parameters as needed. As shown in ACS ISR 2018-04 comma  the number of traps affecting small to medium-size charge packets can be inferred from the shape of warm pixel trails in short darks with a range of background (post-flash) levels. A new comma  more direct approach to pinning the CTE model has been developed to compare these data to scaled long (1000s) darks from the Daily Monitor program. By examining the survival of WPs as a function of row number and post-flash level comma  we can develop a direct model for CTE losses.

description: Despite their widespread use as standard candles to measure cosmological distances comma  Type Ia supernovae are not a homogeneous group of explosions.  There are variations in optical light curve shape and ejecta velocity comma  for example.  The sensitivity of the UV to differences in progenitor systems comma  explosion physics comma  and environmental conditions makes it a vital regime to determine the physical cause and magnitude of the differences and their effect on the optical bands currently used for cosmological measurements. The goal of understanding the range of progenitor and explosion properties of SNe Ia can be advanced by obtaining UV spectra covering the range of Type Ia supernova properties.  The proposed observations will sparsely sample the multi-dimensional parameter spaces of the observed and physical differences between various classes.  The goal is to bring order to these disparate objects by determining which are actually physically related and by what parameters.  Combined with previous HST observations comma  these observations will form the definitive observational sample for building theoretical models comma  constraining progenitor environments comma  and comparing with high-redshift supernovae from past and future observatories including LSST and WFIRST.

description: We propose 10 orbits of HST WFC3-UVIS G280 slitless grism spectroscopy of S1723 comma  an extremely bright gravitationally lensed galaxy at redshift z=1.3293.  The proposed observations will spatially map Lyman alpha comma  escaping ionizing radiation comma  and the non-ionizing UV spectral slope comma  on spatial scales never before obtained for an extreme emission line galaxy. Combining this new spectrum with a published HST-WFC3 G141 grism of Ha will produce maps of Lya escape fraction and ionizing photon escape fraction comma  to reveal how Lyman alpha and ionizing photons are able to escape. This target has the extremely strong rest-frame UV and optical emission lines that are a hallmark of galaxies at the epoch of reionization (zvirgul7--8) comma  but due to lensing magnification comma  can be studied at very high spatial resolution.  The target has a wealth of published data including HST multiband imaging comma  a lens model comma  and MMT comma  Keck comma  Gemini comma  and HST spectra comma  and is an approved target for JWST imaging and spectroscopy with NIRCam comma  NIRSpec comma  and MIRI comma  with all data to go public as they are observed.

description: Ultra hot Jupiters are unique planetary objects that have a dayside temperature exceeding 2200K due to intense irradiation from the host star. An important aspect hereby is the spectral type of the host star comma  which determines the wavelength range at which most of the stellar radiation is emitted. This in turn impacts the efficiency of the planetary atmosphere to absorb the incoming stellar flux. As most of the observed ultra hot Jupiters orbit F-G stars comma  the parameter space of planets around A-type stars has not been explored sufficiently to be able to empirically verify this theoretical prediction. We propose to observe two recently discovered ultra hot Jupiters that orbit A-type stars to study how hot stars can affect the thermal structure and atmospheric composition of the planet.

description: An exciting development in the understanding of the early evolutionary stages of massive stars comma  based on a new study of the Orion BN-KL region comma  is that the disruption of a massive young stellar system can lead to an explosive event producing a wide-angle outflow - an entirely different phenomenon from the classical bipolar flows driven by YSO accretion disks. We have discovered an object comma  IRAS05506+2414 comma  which may be the 2nd clear-cut example of this phenomenon. Our HST optical and near-IR images show a fan-like spray of high-velocity (up to 350 km-s) elongated knots which appear to emanate from a bright compact central source  we find that the physical properties (opening angle comma  outflow speeds comma  knot masses comma  Herbig-Haro-object like optical line emission) of the IRAS05506 wide-angle outflow are very similar to those seen in Orion.  We propose to determine IRAS05506.s distance from a measurement of the knot proper motions using WFC3 to obtain a 2nd epoch F606W image. Only then will we be able to robustly constrain the central star.s luminosity and mass and the dynamical time-scale comma   mass comma  velocity comma  and kinetic energy distributions of its outflows -- needed to test possible mechanisms for the explosive disintegration model for such sources. Deep emission-line imaging with WFC3 will be used to probe the full size and structure of the bullet spray. We will use STIS to confirm the presence of a second outflow engine in IRAS05506doublePoint an intriguing linear feature that looks like a classical YSO collimated jet can be seen emanating from the central source comma  but only a long-slit spectrum of the line emission with sufficient angular resolution can confirm it to be a high-velocity jet.

description: Photodissociation regions (PDRs) are predominantly neutral regions of the ISM in which the heating and chemistry are mainly regulated by far ultraviolet photons. They are extended regions at the interface between bright stars and molecular clouds comma  and contain dense structures and clumps immersed in a more diffuse medium which are subjected to photo-evaporation comma  which brings fresh matter into the diffuse hotter zone. The interaction of stellar radiation with in situ material includesdoublePoint 1) the disruption of grain mantles-clusters and coagulated grains formed in shielded dense regions comma  2) ionization and dissociation of the gas and 3) gas and dust heating. Studies of nearby PDRs have shown that these processes are strongly stratified and active on angular scales that can be as small as virgul1d_comma (0.002 pc-400 au at a distance of 400 pc) comma  indicating that the physical conditions vary over orders of magnitude on small spatial-scales in PDRs. Nearby PDRs are therefore unique targets to study rapid variations in the dust and gas components as a function of the excitation and physical conditions. In light of the importance of PDRs in understanding ISM physics and chemistry comma  we propose to use STIS on HST to study two emblamematic PDRs comma  the Horsehead and NGC7023 comma  at wavelengths covering the dominant energy input into the PDR comma  the optical and UV. These data will provide data that complements an accepted JWST GTO program combining imaging and spectroscopy of both PDRs. We will observe regions matched to the apertures defined in the JWST program from virgul100-1000 nm using four STIS gratings comma  two paired with the STIS MAMA detectors and two with the STIS CCD detectors comma  all four in low resolution.

description: We propose a WFC3-IR imaging study of the hosts of 4 quasars that were recently caught launching newborn jets by the Very Large Array Sky Survey (VLASS).  The targets are broad-line (type 1) SDSS quasars at 0.2<z<1.0 that have transitioned from radio-quiet to radio-loud in the past 10-20 years.  Extensive multi-wavelength follow-up observations in the radio and X-ray probing the jets and accretion states are underway comma  but the properties of the host galaxies remain V1.0.  The unmatched combination of angular resolution and PSF stability of HST is needed to enable accurate quasar-host galaxy decomposition and gain insights into the conditions under which quasar jets are born.  Our proposed observations will measure the morphologies comma  sizes comma  and luminosities of the hosts of newborn quasar jets for the first time.  A total of 4 orbits are required.  Our sample size and observing request are modest comma  but will pave the way for larger studies in the next few years as new VLASS epochs continue to identify new candidates.  We will compare the host properties of our sample with those of previous studies of quasar hosts.  Our proposed study will help guide future campaigns with HST and JWST to determine the host galaxy properties and conditions under which jets are triggered.

description: Starbursts comma  and their powerful galactic-scale outflows comma  are an important mode of galaxy evolution. Yet comma  owing to their frequently large distances comma  we understand little about how these starburst-driven outflows operate. Star formation in these outflows comma  previously observed indirectly using spectral decomposition comma  and predicted in models comma  is an as-yet untapped comma  powerful tracer of the complex physics governing these winds. Resolved star formation triggered within a starburst-driven outflow has now been observed for the first time in M82.s prototypical superwind. Deep wide-field imaging has revealed that the wind-induced stellar populations extend in a trail comma  well beyond M82.s disk comma  displaying an apparent age gradient. This 'trail of breadcrumbs. tantalizingly encodes the history of M82.s outflow.   As the first-ever detection of this phenomenon comma  M82.s outflow-formed stars present an entirely new lens to study its prototypical outflow comma  and a singularly unique opportunity to constrain outflow physics. We propose an efficient comma  12 orbit coordinated WFC3-ACS survey of M82.s trail of star formation in the F475W  and  F814W filters. This program will allow us to measure the outflow.s star formation history (SFH) within the last 300 Myr. Using this SFH comma  we will place the first-ever stringent constraints on (1) the outflow timescale comma  (2) the mass outflow history comma  and (3) the total amount of stellar material contributed by the outflow to the stellar halo. This exquisite dataset will have tremendous legacy potential as a stellar catalog for spectroscopic follow-up comma  and will serve as a case study of this likely ubiquitous comma  yet poorly understood comma  astrophysical process.

description: Two planets have been detected around the 23 Myr pre-main sequence M dwarf AU Mic  their known age makes them good probes for early stages of exoplanet evolution. AU Mic c is the 2.56 Earth radius outer planet orbiting with a period of 18.9 days. It has a mass of about 20 Earth masses. The planet.s relatively low density comma  high levels of X-ray and UV radiation comma  proximity to its bright host comma  and its youth indicate this planet is likely experiencing atmospheric mass loss. This makes it an excellent target for STIS UV observations to look for escaping neutral hydrogen during transit at Lyman-alpha. AU Mic b comma  even closer to its host comma  already has similar observations comma  so observations of AU Mic c will provide the opportunity to explore atmospheric escape process for multiple planets in the same system. With STIS observations of AU mic c comma  we can constrain the planet.s mass loss rate and potentially the dynamics of the upper atmosphere. Observations of AU Mic c will provide much needed additional data to test atmospheric escape models.
