2. Form to Solicit Feedback on WMKO Future Priorities (Feedback requested by May 6, 2025)
As members of the NASA-Keck community, we are asking for your help in prioritizing future technology projects. WMKO representatives have been traveling to all partner campuses to have face-to-face meetings and group discussions to:
- Provide our community with information on future projects that were identified in the strategic plan and that may have evolved since the strategic plan was published.
- Understand what future defined projects and initiatives can benefit you specifically and your campuses.
- Get a sense of what projects have the highest priorities in your community.
- For the NASA community, WMKO representatives will be discussing project priorities with the NASA user group (current NIKUG representation can be found here).
As input to the NIKUG discussion, we want to know what current instruments and what future capabilities are important to you, and to gather that information in advance of the NIKUG meeting, we are asking you to take a few minutes to fill out this form indicating your priorities. Supplementary documentation that provides a little more detail (Keck strategic plan and the presentation shared with Keck partner campuses) is available through the links on the form. Your feedback is requested by Tuesday, May 6.
We appreciate and look forward to hearing from you.
Sincerely,
Statia Cook (on behalf of the NASA IRTF Keck Users Group)
3. Join the First Virtual EMAC Curator Hackathon (May 6, 2025)
"We invite you can join NASA Goddard’s Exoplanet Modeling and Analysis Center (EMAC) for our first Curator Hackathon on May 6th at 1pm US Eastern. This hybrid event will feature an introductory presentation going over EMAC’s latest features and the value and benefits of a Resource Curator Program for both curators and the community. After a break, we will jump into hands-on curating; everyone should be able to quickly get the hang of the system, and the continue exploring and curating resources on their own schedule. Zoom information can be found at the end of this message.
EMAC Curator Program
Have you developed exoplanet software but don’t see it on our repository? Do you see your favorite resource but noticed it has incorrect or missing information? Is there a feature you wish EMAC had? That is where EMAC curators come in. Our small team might miss the latest resources or not be aware of the correct metadata. Community supporters like you ensure that EMAC remains a valuable tool for the wider exoplanet community. In addition to becoming better versed on the current landscape of exoplanet software, Curators will also be recognized on the EMAC website as well as on the categories and collections they help curate. EMAC networking events (like this one!) also allow you to meet fellow software and exoplanet enthusiasts which we hope will foster new open-source projects or proposals.
No programming skills are required to be a Curator; If you do exoplanet or adjacent science utilizing software then you can be a curator!
Agenda
All times are in US Eastern (UTC - 4)
Date: May 6th, 1pm to 3:30pm.

"Using Ocean Dynamics to Map Marine Habitability on Earth-like Exoplanets"
Ashika Capirala (Purdue University)
Abstract: Earth’s oceans have hosted an abundance of biological innovation, and oceans on Earth-like exoplanets may be similar hotspots for life. Habitability for complex, multicellular life requires more than just liquid water, depending additionally on circulation patterns that transport dissolved oxygen (O2) and nutrients within oceans. However, Earth's own ocean circulation has changed through time due to the slowing of Earth's rotation and the rearrangement of continents. Planetary rotation rate affects atmospheric circulation and (in turn) wind-driven ocean circulation, while continental configuration alters surface and deep ocean circulation patterns. Both rotation rate and continental configuration could vary across Earth-like exoplanets, allowing many potential landscapes of circulation and marine habitability. We use a 3D Earth system model to explore these alternate landscapes. We find that slowing rotation enhances ocean circulation and vertical mixing, leading to more efficient nutrient recycling, greater photosynthetic productivity, and higher O2 production. Stronger circulation oxygenates the deep ocean, creating potentially ‘superhabitable’ marine environments, and atmosphere-ocean interactions may also increase O2 biosignature potential on slower-rotating planets. Additionally, we find that changing continents alone can generate highly variable circulation regimes and biogeochemical outcomes. Importantly, for some configurations, the ocean can be highly deoxygenated even under detectable levels of atmospheric O2. We suggest that detecting Earth-like O2, while it may imply the presence of life, does not guarantee complex habitability.
"Wind-AE, A Fast 1D Atmospheric Escape Model with X-rays and Metals"
Madelyn Broome (UC Santa Cruz)
Abstract: Throughout their lives, short-period (< 100 days) exoplanets are strongly irradiated by their host stars. Especially in the first few hundred megayears, photoionization by the young hot stars' strong XUV fluxes can drive transonic winds that outflow from these planets. The mass loss histories of these planets are essential to understanding the evolution and demographics of these populations; however, mass loss rates are not directly observable. They can only be inferred from models. To that end, we present, Wind-AE an open source 1D, multifrequency (thru to X-ray), multispecies, steady-state Parker Wind photoevaporation relaxation code based on Murray-Clay et al. (2009). The speed and reliability of the tool have allowed used in a number of investigations we will touch on including: exploring the impact of metallicity on mass loss rates; modeling observational limits of escaping H$\alpha$ on WASP-12b; constraining whether sub-Neptunes TOI 776b and c that span the period radius valley are water worlds; investigating the mystery of unusually large X-ray transits in HD189733b; and more.

"From Transits to Trends: The Next Decade of Long-Period Exoplanets” workshop
August 5 - 8, 2025, Albuquerque, NM
https://transitstotrends.github.io/
This workshop will be held August 5 - 8, 2025, at the University of New Mexico in Albuquerque, NM. The discovery of a growing number of long-period transiting exoplanets accessible to detailed characterization in recent years has enabled the community to expand the parameter space within which exoplanet properties can be investigated and begin drawing more direct comparisons with Solar System planets. But as studies of these exoplanets often require a larger telescope time investment than their closer-in counterparts, the time is ripe for considering the most pressing questions the community has about this population and how to best address them.
The abstract submission deadline has been extended to May 2, 2025: https://forms.gle/GZbrASrF14LyKbaW8
The application form for travel support requests will also remain open until May 2.
Registration is open until June 13 or when participant cap is reached.

Objectives of Conference:
This conference will bring together experts and enthusiasts of infrared spectroscopy to discuss the vast scientific potential unlocked by space-based infrared observations. From unraveling galaxy evolution across cosmic time to revealing the chemical compositions of star-forming regions and planetary systems, space spectroscopy offers an unparalleled window into the universe. Missions such as JWST, Euclid, SPHEREx, Roman and Ariel are, or soon will be, revolutionizing our ability to study the faintest and most distant objects, or acquire spectra orders of magnitude faster than previous telescopes.
The aim of the conference is to highlight the scientific breakthroughs enabled by these missions and explore synergies across distinct fields—from cosmology to planetary science—through shared methodologies or multi-purpose data sets. It will also strive to address the community's research and collaboration needs, especially regarding large and complex datasets, while promoting the use of advanced data analysis techniques. An additional focus will be on exploring strategies to optimize future observational efforts, ensuring maximum scientific return from these missions.
We hope to see you soon in Pasadena!
