Volunteer Training Series: Recognizing Young People
EDIS, 2016 Developing a sense of belonging is one of the Essential Elements of a positive youth development experience. Creating an inclusive environment in your 4-H club programs and activities can help you achieve this goal.

High Energy Neutrino Emission and Neutrino Background from Gamma-Ray Bursts in the Internal Shock Model [PDF]
, 2006 High energy neutrino emission from GRBs is discussed. In this paper, by using the simulation kit GEANT4, we calculate proton cooling efficiency including pion-multiplicity and proton-inelasticity in photomeson production.

A Significant Population of Very Luminous Dust-Obscured Galaxies at Redshift z ~ 2 [PDF]
, 2008 Observations with the Spitzer Space Telescope have recently revealed a significant population of high-redshift (z ∼ 2) dust-obscured galaxies (DOGs) with large (rest-frame) mid-infrared to ultraviolet luminosity ratios.

Large Cosmic Variance in the Clustering Properties of Lyman Alpha Emitters at z~5
, 2004 We reported in a previous paper the discovery of large-scale structure of Lyman Alpha emitters (LAEs) at z=4.86+-0.03 with a projected size of 20 Mpc x 50 Mpc in narrow-band data of a 25' x 45' area of the Subaru Deep Field (Omega_0=0.3, lambda_0=0.7, H0=

TeV neutrinos from core collapse supernovae and hypernovae
, 2005 A fraction of core collapse supernovae of type Ib/c are associated with Gamma-ray bursts, which are thought to produce highly relativistic jets. Recently, it has been hypothesized that a larger fraction of core collapse supernovae produce slower jets ...

Cosmic Star Formation History and the Future Observation of Supernova Relic Neutrinos
, 2004 We investigate the flux and event rate of supernova relic neutrinos (SRNs) and discuss their implications for the cosmic star formation rate. As reference models, we adopt the supernova rate model based on recent observations and the supernova neutrino ...

The Hubble Space Telescope Cluster Supernova Survey: VI. The Volumetric Type Ia Supernova Rate
, 2011 We present a measurement of the volumetric Type Ia supernova (SN Ia) rate out to z ~ 1.6 from the Hubble Space Telescope Cluster Supernova Survey. In observations spanning 189 orbits with the Advanced Camera for Surveys we discovered 29 SNe, of which ...

The Extended Hubble Space Telescope Supernova Survey: The Rate of Core Collapse Supernovae to z~1
, 2012 We use a sample of 45 core collapse supernovae detected with the Advanced Camera for Surveys on-board the Hubble Space Telescope to derive the core collapse supernova rate in the redshift range 0.1 -15 supernovae, is needed to better constrain the rates.

, 2005 We present deep 3.6 - 8 micron imaging of the Hubble Deep Field South with IRAC on the Spitzer Space Telescope. We study Distant Red Galaxies (DRGs) at z>2 selected by Js - Ks > 2.3 and compare them to a sample of Lyman Break Galaxies (LBGs) at z=2-3 ...
