Learn how your individual actions, attitudes and behaviors can cultivate cultures of inclusion in the groups and organizations you join. This workshop session will cover principles of effective allyship, developing resiliency for ongoing diversity work, and skills for bystander intervention in the face of bias.

Ron H. Smith is the Director of the Howard University Karsh STEM Scholars Program. The Karsh STEM Scholars Program currently supports 122 STEM Scholars throughout their academic journey, with the goal of the Scholars receiving a Ph.D. in a STEM field. Students start in the program during their undergraduate years and continue through the completion of their graduate degree. In this session,...
A closed session for junior members and non-members only convened by the Governing Board postdoctoral representative, Ben Schmitt.
See videoconference room link for connection details.
This session will be held in parallel with the closed junior member feedback session. This is not a closed session, and all attendees are welcome to join.
We will discuss ideas for what kinds of programs we can or should support as a growing collaboration, and how to get more junior and senior members involved in these efforts.
Potential discussion topics include:
- How and when to...
In this talk I will give a brief description of the gamma-ray burst phenomena, will introduce the different types of progenitors, and the model that defines the electromagnetic emission of GRBs. I will focus particularly on the emission in the millimetre range and place this into the context of CMB-S4, giving examples of what we may expect to gain through the observations performed by the new...
CMB measurements have unique and almost completely model-independent sensitivity to new light degrees of freedom. As a result, whole classes of dark sectors and dark matter models should produce a signal at CMB S4. Non-detection would severely constrain the space of possible solutions for fundamental puzzles like the nature of dark matter or the hierarchy problem. Positive detection would...
The mm-band presents an exciting new discovery space for extragalactic transients, including supernovae, gamma-ray bursts, tidal disruption events, and fast & blue optical transients. I will set the stage via glimpses through the new window opened up by ALMA into the science of such transients, followed by prospects for their detection and characterization with upcoming CMB surveys.
For GRB science, what do we need in terms of:
- Alert stream contents & timescale
- Additional technical infrastructure / data products
Do we benefit from a higher-cadence experiment from the Pole? (Higher depth, higher cadence, longer revisit time)
- Review recent results from SPT & ACT
- Questions to bear in mind during the talks
In this talk I will show that we can detect relativistic axions that are a relic of the early Universe with instruments searching for axion dark matter. I will outline several forms such a cosmic axion background could take, demonstrate how the CaB would appear at an axion haloscope, and explain why current analyses would discard any emerging signal as a background.
For stellar-flare science, what do we need in terms of:
- Alert stream contents & timescale
- Additional technical infrastructure / data products
Do we benefit from a higher-cadence experiment from the Pole? (Higher depth, higher cadence, longer revisit time)
The Epoch of Reionization (EoR) -- when ultraviolet photons emitted by the first stars and galaxies transformed the intergalactic medium from mostly neutral to mostly ionized -- is a primary science motivation of many current and upcoming facilities. The landscape of experiments is diverse, with some seeking a detection of the ionization field itself, and others instead going after the sources...
The epoch of cosmic reionization can be probed using the secondary anisotropies imprinted on the cosmic microwave background (CMB) temperature and polarization field. I will discuss the imprints of patchy reionization on the kSZ power spectrum and CMB B-mode polarization. I will introduce two new scaling relations to connect the kSZ and secondary B-mode power spectrum with the physics of...
Recent years have seen an explosion in the number of line intensity mapping experiments, particularly those targeting the Epoch of Reionization. By targeting unresolved emission of a variety of spectral lines, these surveys will provide new windows into the nature of the high-redshift objects responsible for ionizing the interstellar medium. In this talk, I will briefly summarize the status...
The kinematic Sunyaev-Zel’dovich (kSZ) effect contains a contribution from the inhomogeneous reionization process, and encodes valuable information about how reionization progressed. We examine several upcoming opportunities for cross-correlating the kSZ signal with other probes of Cosmic Dawn and the Epoch of Reionization. Specifically, we look at the 21cm signal, measured by radio...
In the era of the high-precision CMB measurements, in addition to the conventional power spectrum, other observables will help to constrain cosmology. For example, the gravitational lensing effect introduces correlations between different modes of CMB fluctuations. This mode-mode correlation has been used to reconstruct gravitational lensing from CMB data. Other secondary effects could also...
Upcoming large angular scale CMB surveys aim at measuring the scalar-to-tensor ratio r, to determine the energy scale of inflation, and the optical depth to reionization tau. To measure these systematics and noise dominated signals, flexible likelihood approximation techniques are required. We present novel methods from likelihood approximations to likelihood-free inference techniques and...
In this talk, I will present the simulation status of the atmospheric effects for the LSPE/Strip telescope. In particular, I will emphasize how this technique can be easily applied at the other CMB ground-based experiments like QUBIC that will observe the CMB from the Atacama sky
Acoustic dampening of the cosmic microwave background (CMB) power spectrum results from imperfect photon-baryon coupling in the pre-recombination plasma. At redshift 5 × 104 < z < 2 × 106 , the plasma has an effective chemical potential, and energy injections from acoustic dampening in this era create μ- type spectral distortions of the CMB. These μ-distortions trace the underlying photon...
