description: The massive comma  compact galaxy Makani hosts one of the largest CORCHETE_OPENOIICORCHETE_CLOSE nebulae comma  and perhaps the largest starburst-driven galactic wind comma  yet detected. This wind extends well into the CGM of its host (r_wind > 20r_stars) and is a snapshot of the CGM-in-formation. The cool comma  dense medium of the wind-CGM interface in Makani (traced in emission by CORCHETE_OPENOIICORCHETE_CLOSE comma  MgII comma  and CO emission) on scales of 100 kpc show an outflow forming the cool CGM in real time. Much of our knowledge of the CGM in other galaxies is derived from statistical studies of the warm-hot (10elev5-10elev6 K) phase. The enormous and lumionus oxygen nebula in Makani is the ideal target to *image* the warm-hot CGM comma  which is difficult in most other sources. We propose to make the first d_commarebirth picture.. of the warm-hot CGM as it is being formed anew by the giant wind in Makani. We will image Makani in OVI 1032 comma  1038 A with ACS-SBC comma  a technique that recently yielded the first OVI image of the halo of a starburst galaxy (Hayes et al. 2016). We will apply the same synthetic narrowband technique which is perfectly suited for Makani comma  whose observed-frame OVI line (at z=0.459) lies at the peak of the F150LP filter. These observations are optimally-timed to meet simulated images of OVI that are emerging from the latest simulations. The morphology of the OVI image and line flux ratios with CORCHETE_OPENOIICORCHETE_CLOSE will constrain the physical state of the gas in the nebula through comparison with models and simulations of the wind-CGM interaction and shock+photoionization models.

description: As the only low-mass disk galaxy in the Local Group comma  M33 is one of the most important and best-studied galaxies on the sky. It is also one of the most confusingdoublePoint since it is nearly bulgeless comma  it is unclear what makes it stable to formation of a strong bar. One stabilizing factor may be the existence of dynamically hot components such as a thick disk or halo comma  but these have long been controversial and hard to detect. Recent individual-star spectroscopy now gives clear evidence of a halo component comma  but its structural properties comma  its origin comma  and its dynamical effects are not yet clear. We propose to use proper motions with 16-year baselines to measure the kinematics of stars in five fields at the edge of the M33 disk. We will probe the relative rotational lag of the hotter components (the halo and a possible thick disk) versus the young comma  thin disk. We will measure the dispersions in the planar and vertical directions separately comma  using dispersions measured directly from proper motions as well as the correlation between the proper motions and LOS velocities from spectroscopy. We will check the halo for non-equilibrium flows indicating a possible origin in a recent merger. We will also provide an independent and more precise measurement of M33.s center-of-mass proper motion. These observations are only feasible now because of the longevity of HST.  They will yield a dataset completely unique in nature for any galaxy like M33 comma  which will shed new light on the structure and dynamical history of this important galaxy.

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. The system and the data are updated automatically as the number of public fungal ITS sequences grows.

description: Close binaries containing at least one white dwarf (WD) are thought to be the progenitors of some of the Galaxy.s most exotic objects comma  such as cataclysmic variables comma  AM CVn binaries comma  hot subdwarf stars comma  double degenerates and thermonuclear supernovae (SN) comma  including the cosmologically important SN Ia. This zoo of possible evolutionary outcomes demonstrates the complexity of trying to study the population of WD binaries as a whole. However comma  without a detailed understanding of the evolution of WD binaries comma  we will remain unable to unravel the pathways towards thermonuclear SN and the conditions under which they ignite comma  and equally comma  we will not be able to accurately predict or model the low-frequency gravitational background from galactic WD binaries. Here we propose to take a step back in time to the last stage at which all of these systems were part of the same population of detached WD plus main-sequence star binaries. The properties of these binaries can reveal their past evolution and measure how common different evolutionary channels are. However comma  at optical wavelengths the WD components are overwhelmed by their main-sequence companions making it difficult to determine their masses. Using TESS data we are able to circumvent this by measuring the rotation rate of the stars and comparing this to rotational broadening measurements comma  to measure the binary inclinations and thus WD masses for dozens of systems. However comma  this method relies on the alignment of the spin and orbit of the stars which is by no means proven. Here we request HST-STIS data to confirm if our method yields the correct WD masses for these powerful probes of WD binary evolution.

description: The joint detection of gravitational waves and light from the binary neutron star merger GW170817 has ushered in a new era of discovery. HST has played a pivotal role in characterizing the optical and near-infrared (NIR) evolution of GW170817 comma  with reported detections of the kilonova and afterglow spanning virgul10-350 days post-merger. In particular comma  at >100 days comma  the afterglow brightness is extremely faint at >26 mag  thus all detections or constraining upper limits at late times were enabled by HST. One major complication in measuring accurate photometry of the faint optical and NIR afterglow is contaminating light from the host galaxy comma  which has complex morphological structure. The only way to properly address this issue is by re-visiting the field after the afterglow has faded to obtain deep multi-band template images comma  against which we can subtract earlier epochs. Motivated by a case study in one of the optical filters comma  here we propose 13 orbits of HST-WFC3 imaging to obtain late-time template images in four filters comma  comprising all filters which have HST imaging beyond virgul100 days and for which no adequate template images exist. These images will enable reliable and uniform photometry of the optical-NIR afterglow to GW170817 for the first time. In conjunction with ongoing radio and X-ray campaigns by the community comma  this will allow accurate inferred properties of relativistic outflows from the merger comma  and the deepest limits on a star cluster at the merger position comma  strongly constraining the binary progenitor.s formation. Given the high-impact nature of GW170817 comma  we waive all proprietary rights associated with data from this proposal.

description: The Space Telescope Science Institute (STScI) Director has decided to devote up to 1000 orbits of Director.s Discretionary time in observing Cycles 27-29 to a new Hubble Ultraviolet Legacy program focused on star formation and associated stellar physics. This new program comma  ULLYSES (UV Legacy Library of Young Stars as Essential Standards) comma  will provide a UV spectroscopic reference sample of young (< 10 Myr) high- and low-mass stars. It will target over virgul150 OB stars in the Magellanic Clouds and lower metallicity galaxies in the Local Group comma  and virgul40 T Tauri stars and brown dwarfs in the Milky Way. In addition comma  ULLYSES will monitor 4 typical T Tauri stars over different rotational phases through at least three rotation periods comma  and over timescales of months to years. The resulting library will provide template spectra of massive stars at metallicities substantially below the well studied comma  while the low mass sample will cover a wide range of ages comma  accretion rates comma  and masses comma  including objects down to well below 0.5 M_sun. The legacy of this large UV dataset on the first 10 Myr of stellar evolution will be enhanced by complementary datasets obtained by the scientific community. In addition to the core goals of the program related to stellar astrophysics of low and high mass stars comma  this data will also enable exciting science in the fields of ISM comma  CGM comma  jets comma  and exoplanets. ULLYSES will be modeled after the Frontier Fields programdoublePoint all data obtained will be non-proprietary. The implementation team at STScI is developing high-level science data products and a sophisticated database and website for disseminating data from the ULLYSES program and ancillary datasets for the ULLYSES target sample from space and ground-based facilities.

description: Monitor the wavelength calibration - dispersion solutions for representative wavelength settings of the STIS MAMA.  Internal wavecals will be obtained at primary and secondary central wavelengths for all the MAMA gratings -- chosen to cover both Cycle 30 usage and settings observed in previous monitoring programs (for long-term monitoring). Most of the settings in this program use the LINE lamp (for a total of approximately 1.5 hours)  two of the shortest wavelength settings use the somewhat brighter HITM2 lamp comma  however.  All but one setting will use a lamp current of 10 mA.

description: Energetically comma  it is possible for a starburst in a dwarf galaxy to blow away and completely ionize its ISM comma  resulting in a very high escape fraction of its ionizing radiation. Finding examples of such galaxies would ease the tension between the energy needed to reionize the universe and the ionizing energy budget available to do so. Pox 186 is an exceptional dwarf galaxy with an active starburst comma  yet a non-detection in deep 21cm HI observations. Its optical spectrum also shows very highly ionized gas comma  with an extraordinary CORCHETE_OPENOIIICORCHETE_CLOSE-CORCHETE_OPENOIICORCHETE_CLOSE ratio (> 20) comma  and evidence of an 800 km-s outflow. Thus comma  Pox 186 has many physical properties consistent with those of the Green Pea galaxies - low redshift analogs of the sources responsible for the reionization of the universe. However comma  Green Peas are dominated by bright star clusters embedded in larger systems many times more massive than the galaxies responsible for reionization. The lower mass of Pox 186 makes it a better match to the high redshift systems. When combined with its close proximity (Dvirgul18 Mpc) comma  Pox 186 offers a unique laboratory to study in detail the extreme properties of a galaxy like those responsible for reionization.    We will image Pox 186 with both narrow and broadband filters and obtain a UV COS spectrum with the G160M grating. The imaging will allow us to study the ionization structure to confirm the density bounded nature of the galaxy.  The UV spectrum will be used to study the structure of the outflow comma  the stars driving the outflow comma  and to directly compare what one could learn from a similar unresolved comma  high redshift system.

description: 323P-SOHO is a near-Sun comet with perihelion activity driven by mass-loss mechanism most likely completely different from that of typical comets comma  and thus is possibly unique in the comet population of the solar system. Postperihelion observations from CFHT in early February 2021 showed that the comet has morphology consistent with ongoing disintegration in rapid evolution comma  in stark contrast to the preperihelion morphology comma  which was simply asteroidal in Subaru data from late December 2020. Thus comma  323P becomes the first short period near-Sun object that has disintegrated. The ongoing event is offering us an unprecedented opportunity to study a near-Sun object in great detail comma  and to constrain properties of the interior as well as the disintegration process. We hereby request four DD orbits comma  taking advantage of HST-WFC3.s ultra-high resolution comma  sensitivity comma  and photometric stability to monitor and characterize the disintegration event at 323P.

description: Studies of massive stellar clusters in the Large and Small Magellanic Clouds comma  spanning a wide range of ages from 100 Myr to 11 Gyr comma  have potentially pinpointed the onset of the multiple populations (MPs) phenomenon.  Focusing on clusters with similar mass (virgul10elev5 Msun) comma   all systems with ages above 2 Gyr were found to host MPs while clusters below this limit do not.  Such a relation with age is not expected in any scenario for the origin of MPs comma  and constitutes one of the most important findings in the field in recent years.  One potential explanation for the observations is that MPs do exist within the young clusters comma  but only below a certain stellar mass limit. We propose to obtain deeper imaging of NGC 1783 comma  a 1.7 Gyr cluster that does not show MPs on its RGB (virgul1.6 Msun) comma  in order to search for splitting along main sequence stars (virgul1 Msun and below) caused by the chemical anomalies. Based on stellar isochrones with MPs abundance variations comma  we expect to observe main sequence splitting with an additional 10 orbits of exposure using our unique optical-UV filter combination. Determining if a stellar mass limit exists for MPs would consistute a major step forward in the search for the origin of the multiple populations phenomenon.

description: The standard astrometric catalog in the field of globular cluster Omega Cen has been used to examine the geometric distortion of WFC3 UVIS and IR as function of wavelength in multicycle calibration programs over last 11 years of WFC3 on HST board.  All observations from these programs have been reduced and provided the multi-wavelength geometric distortion in UVIS and IR detector.  The derived geometric distortion coefficients implemented in the IDCTAB format are used in the HST pipe-line to correct for a virgul7% distortion in WFC3-UVIS and IR images down to <1%.    Additional to multi-wavelength WFC3 geometric distortion comma  all observations  of Omega Cen taken through F606W and F160W UVIS and IR filters respectively  during the last 11 years (all together 12 epochs)  were used to look for time dependency of UVIS and IR geometric distortion and the effect of the scale change due to the thermal breathing. The results of the stability WFC3 geometric distortion published in WFC3-ISR-2015-02 (Kozhurina-Platais  and  Anderson comma  2015) comma  WFC3-2019-09 (Martlin comma  Kozhurina-Platais) comma  have show that the UVIS geometric distortion is stable over 10 years on-orbit within 0.05 pixels  or 2 mas in UVIS. The results of WFC3-IR published in WFC3-ISR-09-19 (M. McKay comma  Kozhurina-Platais comma  et al) have show that the IR geometric distorion is stable over 10 years on orbits within 0.1 pixel or 2 mas.   The purpose of this calibration proposal is to continue the monitor of the WFC3 geometric distortion stability of over time. The observations of Omega Cen through the UVIS F606W filter and the F160W IR filter will be used to derive the skew and scale terms of the geometric distortion and look for any secular changes over time.
