Meeting Goals:
The Learning the Universe collaboration, after three years of work, has made remarkable progress towards our goals. Collaboration members have developed a new, first-principles model for self-regulated star formation within the interstellar medium, emerging from the most extensive and physics-rich set of small-scale disk simulations ever undertaken. We have also developed an innovative new subgrid model for including galactic winds in cosmological simulations, built on our new physical understanding of cloud-wind interactions. We are implementing and testing these new subgrid frameworks in both differentiable semi-analytic models and a cutting-edge hydrodynamics code and have already started a new set of cosmological simulations. The collaboration has also made huge strides in creating tools to rapidly emulate the simulations and employ implicit inference techniques to simultaneously infer both galaxy and cosmological parameters, a watershed and key goal of the collaboration. We have also carried out a reconstruction of cosmological initial conditions to date in an unprecedentedly large volume.

These achievements have allowed us to start up a set of three new cross-cutting collaboration projects: (i) Go Big, the largest implicit inference application to date, (ii) LtU connections, a joint galaxy/cosmology inference that goes to real observations for the first time, and (iii) a suite of high-z simulations to apply our techniques to the exciting new observations of unexpectedly bright galaxies in the early universe. This year’s meeting will bring us together to examine first results from these new initiatives and map out the exciting future capabilities that are now within our reach.

    Participation in the meeting falls into the following four categories. An individual’s participation category is communicated via their letter of invitation.

    Group A – Organizers and Speakers
    The foundation will arrange and pay for round-trip air or train travel to the conference as well as hotel accommodations and reimbursement of local expenses. Business-class or premium economy airfare will be booked for all flights over five hours when within budget.

    Group B – Funded Participants
    The foundation will arrange and pay for round-trip air or train travel to the conference as well as hotel accommodations and reimbursement of local expenses. Economy-class airfare will be booked for all flights.

    Group C – Unfunded Participants
    Individuals in Group C will not receive financial support, but are encouraged to enjoy all conference-hosted meals.

    Group D – Remote Participants
    Individuals in Group D will participate in the meeting remotely.

  • Travel & Hotelplus--large

    Air & Rail
    For funded individuals, the foundation will arrange and pay for round-trip travel from their home city to the conference.

    All travel and hotel arrangements must be booked through the Simons Foundation’s preferred travel agency.

    Travel specifications, including preferred airline, will be accommodated provided that these specifications are reasonable and within budget.

    Travel arrangements not booked through the preferred agency, including triangle trips and routing/preferred airlines outside budget, must be pre-approved by the Simons Foundation and a reimbursement quote must be obtained through the foundation’s travel agency.

    All costs related to changes made to ticketed travel are to be paid for by the participant and are not reimbursable. Please contact the foundation’s travel agency for further assistance.

    Personal & Rental Cars
    Personal car and rental trips over 250 miles each way require prior approval from the Simons Foundation via email.

    Rental cars must be pre-approved by the Simons Foundation.

    The James NoMad Hotel offers valet parking. Please note there are no in-and-out privileges when using the hotel’s garage, therefore it is encouraged that participants walk or take public transportation to the Simons Foundation.

    Hotel
    Funded individuals who require hotel accommodations are hosted by the foundation for a maximum of three nights at Hotel AKA NoMad, arriving one day before the meeting and departing one day after the meeting.

    Any additional nights are at the attendee’s own expense. To arrange accommodations, please register at the link included in your invitation.

  • Reimbursementplus--large

    Overview:
    Funded individuals will be reimbursed for meals and local expenses including ground transportation. Expenses should be submitted through the foundation’s online expense reimbursement platform after the meeting’s conclusion.

    Expenses accrued as a result of meetings not directly related to the Simons Foundation-hosted meeting (a satellite collaboration meeting held at another institution, for example) will not be reimbursed by the Simons Foundation and should be paid by other sources.

    Below are key reimbursement takeaways; a full policy will be provided with the final logistics email circulated approximately 2 weeks prior to the meeting’s start.

    Meals:
    The daily meal limit is $125; itemized receipts are required for expenses over $24 USD. The foundation DOES NOT provide a meal per diem and only reimburses actual meal expenses up the following amounts.

    • Breakfast $20
    • Lunch $30
    • Dinner $75

    Allowable Meal Expenses

    • Meals taken on travel days (when you traveled by air or train).
    • Meals not provided on a meeting day, dinner for example.
    • Group dinners consisting of fellow meeting participants paid by a single person will be reimbursed up to $75 per person and the amount will count towards each individual’s $125 daily meal limit.

    Unallowable Meal Expenses

    • Meals taken outside those provided by the foundation (breakfast, lunch, breaks and/or dinner).
    • Meals taken on days not associated with Simons Foundation-coordinated events.
    • Minibar expenses.
    • Meal expenses for a non-foundation guest.
    • Ubers, Lyfts, taxis, etc., taken to and from restaurants in Manhattan.
    • Accommodations will be made for those with mobility restrictions.

    Ground Transportation:
    Expenses for ground transportation will be reimbursed for travel days (i.e. traveling to/from the airport or train station) as well as subway and bus fares while in Manhattan are reimbursable.

    Transportation to/from satellite meetings are not reimbursable.

  • Attendance & Building Protocolsplus--large

    Attendance
    In-person participants and speakers are expected to attend all meeting days. Participants receiving hotel and travel support wishing to arrive on meeting days which conclude at 2:00 PM will be asked to attend remotely.

    COVID-19 Vaccination
    Individuals accessing Simons Foundation and Flatiron Institute buildings must be fully vaccinated against COVID-19.

    Entry & Building Access
    Upon arrival, guests will be required to show their photo ID to enter the Simons Foundation and Flatiron Institute buildings. After checking-in at the meeting reception desk, guests will be able to show their meeting name badge to re-enter the building. If you forget your name badge, you will need to provide your photo ID.

    The Simons Foundation and Flatiron Institute buildings are not considered “open campuses” and meeting participants will only have access to the spaces in which the meeting will take place. All other areas are off limits without prior approval.

    If you require a private space to conduct a phone call or remote meeting, please contact your meeting manager at least 48-hours ahead of time so that they may book a space for you within the foundation’s room reservation system.

    Guests & Children
    Meeting participants are required to give 24 hour advance notice of any guests meeting them at the Simons Foundation either before or after the meeting. Outside guests are discouraged from joining meeting activities, including meals.

    With the exception of Simons Foundation and Flatiron Institute staff, ad hoc meeting participants who did not receive a meeting invitation directly from the Simons Foundation are not permitted.

    Children under the age of 18 are not permitted to attend meetings at the Simons Foundation. Furthermore, the Simons Foundation does not provide childcare facilities or support of any kind. Special accommodations will be made for nursing parents.
