Science Talk • 12:15 PM, December 13th, 2017 • Morrisroe LCR
A Search for High-Redshift Galaxies And An Accidental Galactic Survey of Dwarf Stars with Hubble // Current searches for high-redshift galaxies use a combination of near-infrared filters with one or more optical filters to check for contaminants. One of these contaminants are faint dwarf stars in the disk and halo of our own Milky Way Galaxy. Thus in the search for the galaxies that caused the Reionization of...

The Physics of Colliding Galaxies // Massive galaxies like our own Milky Way are thought to be built through the merging of smaller galaxies. Despite this incredibly important role in the assembly history of galaxies, however, very little is known about the physics of mergers between low mass galaxies. I will present results from the TiNy Titans Survey (TNT), the first large scale study of interactions and...
Science Talk • 12:15 PM, December 4th, 2017 • KS300
Near-Earth Asteroids (or, Why Dinosaurs Should Have Studied Astronomy)
Science Talk • 12:15 PM, November 29th, 2017 • Morrisroe LCR
Watching the first kilonova, an explosion discovered from the gravitational waves from merging neutron stars // In August 2017, the LIGO and Virgo gravitational wave observatories detected their first neutron star collision, which were predicted to produce optical counterparts that we could observe with traditional telescopes. We quickly began searching for the optical counterpart of the gravitational-wave...
Science Talk • 12:15 PM, November 28th, 2017 • Morrisroe LCR
Finding Terrestrial Planets with Precise Radial Velocities // Precise radial velocities revealed the first exoplanets around Sun-like stars, and most of the first few hundreds. In the past few years, the Kepler mission has changed the landscape of exoplanet discovery and revolutionized our understanding of exoplanets as a population. What is next for precise radial velocities (PRV)? In the near future, PRV...
Workshop • November 15th, 2017 • KS300
In this short talk I will summarize my on-going efforts in science outreach and discuss IPAC’s exceptional opportunities through the Universe of Learning, with a focus on multimedia.
Science Talk • 12:15 PM, November 15th, 2017
In this talk, I will discuss two of my major on-going programs: i) my current work establishing the formation redshift of massive galaxy disks and ii) a cross-disciplinary program on dark matter involving astrophysicists and philosophers of science.
Science Talk • 12:15 PM, November 8th, 2017 • Morrisroe LCR
From Cosmology to Galaxy Evolution with Self Organizing Maps // In this talk I utilize Self Organizing Maps (SOMs), a class of unsupervised neural networks, for dealing with specific challenges in astrophysics from meeting the cosmological survey requirements to measuring galaxy properties. To infer cosmological parameters not limited by systematic errors, WFIRST and other Stage IV Dark energy experiments...

Science Talk • 12:15 PM, October 11th, 2017 • IPAC Morrisroe large conference room
Strong gravitational lensing offers an unique view on the small scale clustering of matter at cosmological distances without relying on luminous structure. This is a regime where different dark matter scenarios can have diverting predictions based on the particle nature (self-interacting, thermal relic, etc) and where tensions in the local group have been reported. Recently, strong lensing has became...
Conference • October 9th - 12th, 2017
This NExScI meeting will gather experts in the field to understand community needs for follow-up ground-based high resolution imaging and spectroscopic observations in the era of K2 and TESS and leading into JWST, PLATO, and WFIRST. Register by Aug 18, 2017.
Science Talk • 12:15 PM, September 20th, 2017
I will present my phenomenological model for AGN at z ~ 0 which is based on the Eddington ratio distribution function. My results show that black hole growth at z ~ 0 can be described by two Eddington ratio distribution functions: one for X-ray and one for radio AGN. The distributions vary in shape, however they are both mass independent. This implies that more massive galaxies are neither more likely to host...
Conference • September 18th - 19th, 2017 • Beckman Institute Auditorium
Exoplanet science continues to be a rapidly increasing field in Southern California. To capitalise on this, we are organising the third annual Exoplanet Orbital Interaction, to allow members of the exoplanet community to get to know one another and to learn about the many opportunities for collaborations.
Science Talk • 12:15 PM, August 14th, 2017 • Morrisroe LCR
Our four undergraduate student interns, sponsored by the UC Riverside FIELDS program, will give summaries of their projects.
Workshop • August 7th - 11th, 2017 • Pasadena, CA
The Sagan Exoplanet Summer Workshop organized by the NASA Exoplanet Science Institute at Caltech/IPAC begins Aug 7 at Caltech. More than 80 participants expected to convene in Pasadena to learn about planet searches and microlensing, with application to WFIRST, Gaia, and Euclid.

ALMA Observations of Protostellar Disks and Jets in the Early Stages of Star Formation // Protostellar disks and jets are seen around protostars in the early phase of star formation. However, when and how they are formed are still uncertain. With Atacama Large Millimeter/submillimeter Array (ALMA), we have observed and spatially resolved them in a few very young protostellar systems at unprecedented...

The Gemini Planet Imager Exoplanet Survey, Automated // The GPI Exoplanet Survey (GPIES) is a multi-year 600 star survey to discover and characterize young Jovian exoplanets and their planet forming environments. I will describe the GPI Data Cruncher, an automated and real-time data processing framework that combines multiple data reduction pipelines to process all spectroscopic, polarimetric, and calibration...
Science Talk • 12:15 PM, May 18th, 2017
The JPL MIRI Project Scientist (not me individually) was awarded 60 (wall clock) hours of Guaranteed Time Observing on JWST. In this talk, I will give an overview of our science plans, how they follow from WISE and Spitzer studies, the observing strategies we chose in light of the significant overheads associated with JWST, and some lessons learned in using the ETC and APT planning tools that will be of value...
Science Talk • 12:15 PM, May 17th, 2017 • MR LCR
The Herschel-SPIRE instrument mapped about 8% of the sky in Submillimeter broad-band filters centered at 250, 350, and 500 microns (1199, 857, 600 GHz) with spatial resolutions of 17.9”, 24.2”, 35.4” respectively. In total, we used the 6878 standard configuration scan maps that are available, including calibration observations. The SPIRE Point Source Catalog contains the result of a systematic and homogeneous...
