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.
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.
Science Talk • 12:15 PM, August 2nd, 2017 • Morrisroe LCR
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...
Science Talk • 12:15 PM, May 24th, 2017 • Morrisroe LCR
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...
Conference • May 4th - 5th, 2017
Join us for the 17th annual Greater IPAC Science Symposium! The symposium will be held May 4-5, 2017 in the Cahill Hameetman Auditorium, and is open to all research astronomers to attend.
Science Talk • 12:15 PM, May 3rd, 2017 • Morrisroe LCR
Title: "The Design, Early Direct Imaging Science, and Future Developments with SCExAO" Abstract: SCExAO is an extreme adaptive optics system recently commissioned and available for open use on the 8.2m Subaru Telescope on Maunakea. In this brief talk, I summarize the architecture of SCExAO (wavefront control, coronagraphy) and science instruments currently in use and planned for use in the near future. ...
Science Talk • 12:15 PM, April 12th, 2017
Tidal Disruption Events are mostly detected by optical transient surveys and usually among quiescent early type galaxies. I will discuss how mid-IR, time series photometries from WISE survey can be used to study these fascinating transient events. I will present the results from one case study of a TDE candidate in ULIRG F01004-2237.
Workshop • April 11th - 13th, 2017 • KS 410
World leaders of education and public communication in astronomy and high-energy physics will gather at IPAC from April 11-13, 2017 to address fundamental questions facing outreach programs for large, international science projects.
Science Talk • 12:15 PM, March 15th, 2017 • MR LCR
Lurking in the Shadows: Long Period Gas Giant Planets as Tracers of Planet Formation // Over the past decade surveys using a variety of techniques have uncovered a diverse array of exoplanet systems. Many of these new systems are difficult to explain within the framework of standard planet formation theories, and have forced theorists and observers alike to re-evaluate their narratives for planet formation...

Science Talk • 12:15 PM, March 1st, 2017 • KS 410
In this talk, we describe the known characteristics of the TRAPPIST-1 system, and place the discovery in broader context, asking: how Earth-like are the seven planets and could they support life? We review advances in measurement and data analysis techniques that have made Spitzer the observatory best suited for long term monitoring of Earth-size planets around cool stars. Finally, we discuss IPAC’s work...

Insights into the high-redshift Universe using Spitzer and Local Galaxies // How do the first galaxies form? What is their connection to reionization? With today’s large samples of galaxies at z > 5, this is one of the burning question in modern astrophysics. Current spectrographs are not able to probe the spectral properties of the very first galaxies until the advent JWST. However, by combining deep Spitzer...
Science Talk • 12:15 PM, February 1st, 2017 • MR LCR
Exoplanet Genetics: What Host Star Chemical Abundances Reveal about Exoplanets // Through the process of star and planet formation, we think that the chemical abundances, or ``genes’’, of host stars are passed on to their orbiting planets. One prominent example of this is the giant planet-metallicity (iron abundance) correlation, but could other stellar ``genes’’ help explain the growing menagerie of...

iLocater: Breaking the 1m/s RV precision barrier: Current radial velocity (RV) instruments for exoplanet science are seeing-limited in design. While previously vital to efficiently couple light into an instrument, these designs lead to multiple systematic errors which combined, pose challenges to overcome the 1m/s RV precision barrier which is required to detect Earth-like planets within the habitable-zone of...
