Neutrino probes of Cosmic Explosions
The collapse of massive stars and their subsequent explosions are among the most energetic phenomena in the Universe and impact many topics in astrophysics, from the chemical enrichment of galaxies to the generation of cosmic rays. Physically, all four fundamental forces of nature play important roles in shaping the core collapse, and the complexity has meant a complete understand of how the collapse reverses to drive an explosion eludes us to this day. On the other hand, the same complex richness makes the core collapse an inherently multi-messenger phenomenon. I will introduce current and upcoming neutrino and multi-messenger probes and discuss how they allow the study of the explosion's interiors and offer new insights into the core collapse and outcomes. In the process, I will highlight the interplay of astrophysics and particle physics. Multi-messenger astronomy is well-positioned to become a new window in which to study the Universe, promising to bring new insights - and potentially surprises.

The Cosmos and You: Why Investing In The Search for Intelligent Life Beyond Earth Is Important To Long Future Of Humanity
The story of humanity began billions of years ago; you are intimately connected to the cosmos that made you. The only near term method of discovering whether we Earthlings can outgrow our technological adolescence and enjoy a long future is to determine the average longevity of technological civilizations in the Milky Way Galaxy. Today, we do not know whether there are any other technological civilizations; we could be unique. In physics we count 1,2, ∞ when only one example of a phenomenon is known, it could be singular, but as soon as a second example is found, we know there are many. N=2 is the important number for SETI. There are many indicators and futurists that suggest this could well be our last century as a technological civilization, but the successful detection of evidence of another technological civilization would mean that someone else has survived into old age, and therefore could provide abundant motivation for us to do so ourselves.

Challenges of simulating the martian atmosphere
Numerical modeling of planetary atmospheres has long been a prominent
tool for planetary exploration as well as the corner stone of all
weather prediction and climate studies on Earth. The most comprehensive
atmospheric numerical models are called General Circulation Models,
and they tend to incorporate a numerical representation of the most
important processes occurring in a planetary atmosphere. Each planet has
its unique characteristics and challenges when it comes to building
a GCM for its atmosphere. This presentation will list the particularities
and challenges of simulating the martian atmosphere.

Data assimilation applied to planetary atmospheres
Data assimilation in atmospheric science refers to the process through
which systematic observations of different nature and sources are combined
with a numerical model to produce a more accurate simulation. Data
assimilation has been the key that enabled weather forecasting on Earth
and is extensively used for climate studies. Only recently has this
technique been attempted for Mars and contemplated for other planets.
This presentation will explain the workings of Data Assimilation and the
benefits that can be reaped from its application to other planets.

Dark matter signals from the Inner Galaxy?
Dark matter makes up roughly 80% of the matter in the universe, yet the details of its particle nature remain unknown. Many particle dark matter candidates can pair annihilate or decay to produce Standard Model particles, including gamma rays, charged particles, and neutrinos. The detection of these indirect signals of the annihilation or decay of dark matter in our Galaxy and beyond is a promising method for identifying dark matter, understanding its intrinsic properties, and mapping its distribution in the universe. Recent indirect searches with gamma rays have yielded several tantalizing hints of dark matter signals from the Inner Galaxy, however a confident detection remains elusive. I will discuss these recent results and possible alternatives to the dark matter interpretation of the claimed signals, as well as new approaches and prospects for robustly identifying a dark matter signal from the Inner Galaxy with upcoming experiments.
