description: Accretion inevitably produces disk winds comma  which has vast consequences. These outflows can regulate the accretion process comma  affect the long-term orbital evolution of the X-ray binary comma  and impact their cosmic envi- ronment. However comma  it is not established exactly how disk winds are launched comma  and how much mass is carried away by them. We propose to study the disk wind of a persistently accreting neutron star across the elec- tromagnetic spectrum with XMM-Newton comma  HST and VLT. These simultaneous multi-wavelength data will determine the launch mechanism and mass content of the disk wind. This show-case study will highlight the impact of studying disk winds across the electromagnetic spectrum and pave the way for future observations.

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: Recent advances in high-cadence surveys have revealed a new class of luminous and rapidly-evolving transients comma  which are not intrinsically rare but pose significant challenges to conventional supernova models. In 2018 comma  an extreme member of this class comma  AT2018cow comma  was identified. AT2018cow was the first rapidly-evolving transient discovered promptly at a small distance comma  facilitating intensive multiwavelength follow-up. However comma  despite being the most extensively studied transient of its class comma  its true nature is still debated comma  with possibilities ranging from tidal disruption events to the failed explosion of a massive star.  Late-time observations of rapidly-evolving transients offer a means to break this degeneracy comma  and HST images taken during 2020 (more than 700 days post-explosion) reveal a UV-bright point source at the precise position of AT 2018cow. However comma  the nature of this underlying source is ambiguous as it can be interpreted as either the emission from the transient or an underlying stellar population--both of which would place significant constraints on the origin of AT2018cow. Recently comma  a shallow HST SNAP observation in 2021 showed tentative (2-sigma) evidence for fading in the optical (where the source is faint). Here we request a single epoch of HST-UVIS imaging to confirm the transient nature of the source and measure its rate-of-decline comma  necessary to constrain the power source. Extrapolations based on physically and observationally motivated models show that the source may be detected during this Mid-Cycle at 25.5-26.0 mag (AB). We emphasize that HST is the only current instrument with the resolution and depth capable of probing this source.

description: Observations of the spectrophotometric white dwarf standard star WD0308-565 will be obtained at all cenwaves that are moving to LP5 comma  and G140L-800 comma  which is moving to LP3.  All FP-POS will be used for the observations except for G130M-1291-FUVB comma  for which only FP-POS=3 comma  4 will be used in order to comply with the COS2025 rules.  The data will be used to determine the 2D cross-dispersion spectral profiles and traces required to perform two-zone extraction comma  as well as the sensitivities and flat-fields for accurate flux calibration.  Additionally comma  the data will be used to determine the spatial resolution of the detectors.  The main requirement for this program is to achieve S-N of about 50 per resel comma  which is driven by the requirement for obtaining profiles that are sufficiently accurate that the contours can be located such that the enclosed flux errors are less than 1%.  This program ties in with the FUV spectroscopic sensitivity monitoring program at LP4 during which near-contemporaneous observations at the new LPs will be obtained to monitor any rapid evolution in the gain.

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: The goal for this program is to monitor the degradation of the Charge Transfer Efficiency (CTE) and the efficacy of using post-flash mode over time. These are monitored using a series of WFC3-UVIS darks with NO post-flash taken before and after the monthly UVIS anneal. There is another program that collects post-flashed darks to monitor the hot-warm pixel growth and median dark current of the detector comma  and so this is a supplementary program to that one comma  to compare un-flashed internals to these post-flashed ones. When used in conjunction with the post-flashed internals comma  the un-flashed internals allow for an assessment of how well the post-flash is mitigating the CTE losses.  The products generated from this program include on-going analysis of the post-flash efficacy and an updated report on the CTE degradation over time. This is usually in the form of an ISR.  Prior result is WFC3 ISR 2019-10doublePoint Post-flashed superdarks contain at least 50% more hot pixels comma  and had 2 e--hr lower dark current for each anneal cycle.

description: The bright comma  nearby star V723 Mon has a 3 Solar mass dark companion comma  most easily explained as a mass gap black hole.  There is no optical spectral evidence for a stellar companion comma  nor are there continuum eclipses comma  but there is  evidence of a non-stellar comma  blue d_commaveiling.. light and eclipses of the Balmer lines.  Extraordinary claims require extraordinary evidence comma  and so it is important to better characterize the excess UV emission.  Because all but one (UVM2) of the Swift UV filters have red leaks comma  the shape of  the UV spectral energy distribution (SED) cannot be measured with Swift in the presence of V723 Mon.  A rising UV SED would strongly suggest the presence of a hot stellar companion.  More generally comma  the UV emission is not dominated by the red giant and so is the best place to search for spectral features from any stellar companion. If it is not stellar emission comma  the UV is also an important probe of the origin of the claimed d_commaveiling.. light source.  These questions are easily addressed with two one  orbit STIS-CCD-G230LB spectra comma  one in eclipse and one out of eclipse.

description: Very massive stars (VMS comma  >100 Msun) dominate the ionization and mechanical feedback in star-forming regions for the first few Myr. Evidence for VMS has been found from UV observations of young (< 3 Myr) comma  massive star clusters (>5x10elev4 Msun) comma  in the LMC and two nearby starbursts. Larger samples of these stars are needed in order to determine the upper mass limit of the IMF and complete our understanding of massive star evolution. In addition comma  since JWST will obtain numerous UV rest-frame spectra of young high redshift galaxies comma  it is essential that we investigate whether VMS are common in local comma  low metallicity analogs comma  while we still have access to the UV domain. SBS 0335-052E is one of the nearest most metal-poor analogs and contains several super star clusters (SSC) of 10elev5 M_sun. From ground-based optical spectroscopy comma  candidate Wolf-Rayet  (WR) have been found in cluster 3 of the galaxy (SSC3). Given its young age comma  large mass comma  and WR-like signatures comma  SSC3 could host VMS. We request co-spatial STIS G140L UV + G430L optical 52x0.2 long-slit spectroscopy of SSC3 in SBS 0335-052E. The requested observations will cover the high-ionization UV emission lines of C IV comma  He II comma  and O IIICORCHETE_CLOSE comma  and the optical He II 4686 line. Dust attenuation will be obtained from the UV to optical He II ratio. We will use the co-spatial UV + optical data to test if WR stars alone can explain the observed properties of SSC3 or if VMS are necessary. The observations will provide important constraints to state-of-the-art spectral synthesis models of the kind that will be used to interpret rest-frame UV spectra of the most distant galaxies comma  with future large telescopes.

description: We propose high-resolution ACS imaging to resolve the nature of a newly discovered double quasar system at z=5.66 comma  J2037-4537 comma  which could be either a close quasar pair or a gravitationally lensed quasar. Ground-based observations show that J2037-4537 consists of two point sources separated by 1.26d_comma comma  both of which have a spectrum of a z=5.66 quasar. However comma  limited by the seeing comma  it is uncertain whether the lens galaxy exists. The two components are either a physical quasar pair or lensed images of the same quasar. In the former case comma  J2037-4537 will be the highest redshift quasar pair comma  which will place strong constraints on the model of AGN formation and evolution comma  and will enable follow-up observations to study galaxy mergers that trigger quasar activity comma  to probe the kpc-scale structure of the intergalactic medium at z>5.5 for the first time comma  and to search for protocluster traced by the quasar pair. In the latter case comma  J2037-4537 will be the second lensed quasar discovered at z>5 and will be an excellent case study for the high-z SMBH population comma  aided by lensing magnification. With an Einstein ring size of 1.26d_comma comma  J2037-4537 will provide the best chance to detect the stellar light from a quasar host galaxy at high-z. The key to distinguishing the two scenarios is to detect the lens galaxy. However comma  the lens galaxy is likely only 0.3d_comma away from the fainter quasar image comma  which is impossible to get resolved from the ground. Here we propose to use ACS-WFC to confirm (or rule out) the presence of the foreground lens galaxy. With a modest request of 1 orbit comma  we will identify J2037-4537 as either a lensing system or a close quasar pair and prepare for follow-up observations.
